posted February 05, 2004 05:51 AM
I just got a set of 461 heads.I know these are good heads.I just want to know how good they are?I am used to using the 601 or 416 small 305 heads.What should I expect out the change.Oh it is a 355(basic claimer motor).
These are my first set of camel back heads, and I waited forever to find them at my price.What could I do to make these heads better, or should I leave them stock.

I must be asking stupid questions or something. I say that because the posts that I put up usually go unanswered. So I guess if my questions are so lame then I will just drop this forum.BYE.

I can't compare them to the other heads you have, but I really liked mine.

I dropped a valve and wrecked one head, and in the process of finding another one to replace I talked to alot of people.

They all said the 461 is a really good head, but get them checked for cracks before you invest any money in them, the one head shop I talked to said he throws away about 1/3rd of the 461's he gets in, because of small cracks.

First thing spend the money and get them mag'd..

461s are really good heads... they usually need alot of work to be great though. Screw in studs, 2.02-1.6 valves, hard exhaust seats aren't a bad idea, pocket porting. With all that done, they're hard to beat.

The 601's or 416's can also be made to work very well at lower RPMs. If you stuff 1.94-1.6 valves, screw in studs, pocket port and mill the 601's, they're pretty good below 6000rpm. Below 6000, the extra point or so of CR is noticable. The 601's I ran were about 52-54cc with the bigger valves and a .012" decking. I switched to 2.02-1.6 461s that were 62-63cc. I didn't notice much of a difference from in the car (around 6200 is my max rpm). But, when I was making my highlights tape for sponsorship package, I noticed that it seems to pull harder halfway down the straight, but not quite as hard off the turn. With the 601s, it looked like it jumped off the low side of the turn better where with the 461s it liked to run higher and faster. But that's just me and I'm sure some of it was me getting better as the year went on.

depending on your rules,vortec heads have become the best choice around here for stock classes.they flow as good or better than older heads that are getting hard to find.not to mention scoggin dickey sells them for around 500 bucks!!!!!!!!!!!!
