I am in the process of building up my 327 in a 68RS camaro. My goal is to get 375-400 HP out of the engine. A local shop said to start with a purchase of aluminum heads at a cost of 1800.00. Before I invest in that, what are my options here?

I don't know if you need aluminum heads for the street. They ron hotter and they warp really easily. Unless you are running really high compression I would go with a nice set of steel head... s/r torker II's or vortecs or something like that. Don't think aluminum is necessary though. Good luck

You need to find a different shop. Edelbrock Perf RPM Alum. heads: $930 Trickflow 23 degree Alum. heads: $850 Trickflow Twisted wedge Alum. heads: $950 Air Flow Reasearch 190 or 195 Alum. heads $1250. AFR race ready 210 or 220 Alum. heads $1450. Brodix Track 1 $1250 etc. etc... obviously they are trying to rip you off. I do think aftermarket heads are the way to go. Iron or Aluminum. Although I am not impressed with stock SR torkers.

Depends if your after torgue or horsepower, big runners will get higher rpm horsepower. While smaller will give you more torque but less flow at high rpm's. I had Darts 200 cc intakes on my 327 and man would that think wind up (how do you spell that). But low rpm torque wasnt there, until I got lower gears.

But they are right, dont get the alum. and find a machine shop. The casts are a lot more forgiving, and when you need work done to them. You wont have to find a specialty shop to do aluminum heads.

Thanks for all the replies. It sounds like cast heads may be the best plan for my application. If I install forged pistons that come up within .010 of the deck, any suggestions on the chamber size of head I should use? Again, my goal is 375-400HP.

Thanks

Dan
