Been surfing the web for weeks looking at all the choices in heads. I have a 406 with 3cc domes, 3.75" stroke and am really unsure about just how much air I need to put to it and how much if any port work is required. There are a lot of out da box heads that seems like they would work. How much intake volume should I be looking for and how many cc chambers. This engine had 14:1 compression with 58cc heads.

Check out the AFR heads. Best on market. We run hogged out 220 runners, a little too much volume, wish we had a bit more velocity. Our 406 will run 7800 all night long, and just loves those AFR's.

Do most run 23 degree valve angle?

I to went thru the same thing on our Engine this year, and going thru it now for another "BIG" engine.

Basicly, less valve angle, more dollars.

You gotta decide on what you can afford, 23* 220cc heads, with a 2.08 INT & 1.60 EX valves should be perfect for your 406.

Also it makes a big difference between gas and alcohol, on the head sizes. Alcohol likes bigger runner sizes.

Personnally, i like the Dart Pro 1's, made well and no troubles. Buy bare thou, and put good parts in them, valves springs etc.

Anything less than 23* degree stuff will make more power if your rules allow. But anything less than 23* starts to add up between the heads themselves, the rockers, intake and everythign else to go with them. If your limited to iron heads try to find yourself a set of pro 14* heads, and hold on. If you stuck with 23* stuff then at 14:1 on a 406 you could easily run something like the 230 Iron Eagles, especially on alchol, or anythign equivalent in aluminum. Aluminum is lighter but if 2 heads are exactly the same, one aluminum and one iron the iron will make more HP.

Ditto on what dirtbuster said. The only real advantage is aluminum heads help cool the engine and they car be repaired.

Talked to my machinist and here is what we came up with. Brodix Track 1X bare heads 227 intake runners with 2.100 intakes and 1.6 exhaust valves and he'll mill to 58cc. He's got a good source for used titanium vales (a bit long but no problem for him to set up)and a 60/40 valve spacing stud girdle. What yall think about this particular setup?

we have some AFR heads on our 406 motor. we bought them in 01 when we built the motor but have ran it just two seasons(total of about 35 races). at that time we bought the midgrade aluminum head, milled and machined etc etc and my guy then did about 40 more hrs worth of polishing and grinding. we really like them and this motor has good pulling power at low rpm through and off the corners etc. we only turn this motor about 6800ish as well. heads are very nice for the dollar.

Sounds good A&M, put a 2925 Edelbrock intake on there with them, gasket match and clean the bowls up alittle on the heads and you shold be rockin.

Pay really close attention to the cam you put in there with it as well.

We just put a set of pro 14* on our car. they are a pain to get on and cost alot ,but went from being about a 10th place car to pulling the the cars considered fast down the straights on a 3/8 mile track. I know there was a topic on how much hp mods run, but we put our car on a chassis dyno and made 440hp with our old 23* pro heads and the only time we could run with the leaders was when it slicked up. So in the part of the country where we run you better have a stout horse pushing 575-600 hp on the ground.

Those 11X Brodix heads are the best 23* heads money can buy, thats a hella deal.

They will require offset roller lifters i believe thou, .100 offset on the intake if i remember right.

Just for info, Chevy High Performance magazine did their own independant test of all the top aluminum heads. Results? AFR's are number 1. Canfields number 2. Brodix are number 3. I think with Brodix, you are paying for the name, and used to be the best. Spend less $ and buy a better head.

Thats inacurate.

The test is anyway, the 11X Brodix is not even on the radar of anything on the street.

I'd trust the advice of any reputable engine builder over some magazine any day. It's pretty much generally accepted that the 11x are the best 23* head. It'd be an interesting study to see who puts more advertising dollars into that magazine. Also which heads were they comparing, the 11x is nowhere close to a track 1.

As far as needing offset lifters, you shouldn't need them with the shaft mount rockers. The offset is build into the lifter.

Terrell where are you located, I know someone looking for a set.

My bad, they were testing Track 1's. Bob Pierce is now a Mullins dealer. Denny Schwartz and Chad Kinder both run his engines. The big dog ($16,000) uses AFR heads, and his lesser priced engines use Canfields. Denny regurally turns 8,500 + RPMs out of his. I'll find out if they (CHP) tested AFR to the 11x and post results.

Just checked tech archive at Chevyhiperformance. They took all the top heads(brand new), and ran them all on the same flow bench, so there could be no mistake. AFR did out flow the Brodix 11x. Neat article . Check it out. But I know it all comes down to personal preference on what you want to run.

I checked out the article and the AFR numbers are a little better than the rest but the biggest factor to me is the price.
Don't plan on running for UMP national points, just want a good strong mouse. Brodix can't compete with the prices I saw on their website.

I've run Canfields for years, super nice people to deal with. Seem to be better known in my area for drag racing vs oval track, but I give them a thumbs up.

No limits. One car I am working on this year is running 18* and I have a friend running a new sb2.2 motor this year. The 18* is by far the smoothest motor I've worked with for the power level.

I have a line on a bowtie block with 2 cylinders that may need sleeves, a set of brodix 11x heads with matching SUPR intake for $1,300.00 even if the block is too messed up I'll probably take the guy up on the deal. Thanks

brodix 11x are the best flowing 23* head out there. a little history lesson all AFR is the old brownfield co. a guy bought brownfield about 10 yrs ago then renamed it AFR. AFR are some very nice heads for the money but they are mainly a street/strip head i would take a set of 11x over AFR
