I recently took my double humps to the machine shop for some work. In doing so, I saw that I had to buy gaskets for putting the motor back together. Well, this flat top, two barrel street stock motor had the expensive ($35/ea.) Fel Pro #1003 head gaskets. I remember when the motor was put together originally, the builder gave me the price of the gaskets, but I thought he meant for a pair. Oh well, I ended up taking them anyway, so I didn't look like a cheap skate, and I know they're a better gasket. My question is: is it necessary to use those pricy gaskets??? My motor doesn't have massive compression, and both the block deck and heads have been surfaced. With the gasket thickness being the same, would I be okay with using the regular blue gaskets that come with a full Fel Pro kit???

Being on a budget, I don't want to have a Benjamin in a tube of silicone, head, intake, and header gaskets!

nothing beats a fel-pro gasket but i dont think you would need the high priced one on a 9:1 motor i never had atleast

You probably don't need them,now of you had a 400 i would definitely go with the 1004 but a 350 can get away with cheaper ones with no problems.

How about those thin metal shim head gaskets? They're like .017" which helps a bunch for quench when the piston is below the block deck. I heard that you've got to coat all surfaces with Gaskacinch and they seal fine. Does anybody use these?

Rol makes a high temp head gasket that works as good if not better than the fel pro and its only 15.00 each

Felpro makes one that is about 15$ cant remember the number though it is in their standard overhaul gasket kit. It is about .040 thick. They have held up fine in the motors i have seen. I know guys have used the steel shim as well and they have gotten along god. But your right you do need to make sure both the block and head are good and square and use a sealer on the gasket before installation. If you want somethin in between there is a coated gasket about .026 thickness. Not sure if it is a felpro or not. Have gotten then from NAPA before.

thickness is .015.the number for a stock one is 7733pt-2 or try hipo #8651pt

Ive used .018 steel gaskets from gm performance parts that have worked well.The only thing i dont like is you must torque the heads every 5 races or so.The permatex copper spray from autozone works good as a sealer.

For years I have used the Felpro KS2600 kit for engines as you are describing. You can buy just about any where for about $35.00 and that is a come engine kit. Never had any issues.

How high of compression are you running? years ago I used to run the standard headgaskets that came with the ks2600 on a 12 to 1 motor. Never had a problem. The motor I have in now is right at 11 to 1 with the felpro 1094 coated shim gaskets. My last motor ran 2 years before I tore it down and it had the victor steel shims. They are under $10 at carquest. The felpro 1094 is .015 and the victor is .020 thick.
If your block and heads are flat and smooth and your not running real high compression then head gasket choice isnt real critical. Just dont run the standard thick victor head gaskets. had a set on for one night and when i pulled the heads off i had to grind every inch off of the heads and block. the felpros clean up much easier.

the motor I'm goin to refreshen i know i can get away with the stock fel pro head gaskets. the reason why i was asking is i was goin to order a re ring kit from midwest and the kit had the detroit race gasket set. i've always used fel pro's but racing on a very low budget i have to watch what i buy and save money.

I have used the detroits from midwest and prefer them to felpro, used them in a 14 to 1 406 no problems.

ive used those fel pro shim gaskets on almost the same combo as you and never had a problem. just use that aerosol copper spray sealant on them when you put them on and youll be fine

Ferrea makes a decent line of gaskets too. I switched to them last year and have had good results. They offer various bore sizes and thicknesses and they're about 2/3 the price of the Felpro 1004

We run gaskets from NAPA and they are metal composite types. $9 a peice and they have they have NEVER failed. We arent allowed to true the heads or the block, so thats saying alot.
