aluminum head choice
I have about $1000 to spend on aluminum heads for my 383. I currently have 64cc camell humps that are slightly ported, they have been milled twice so may be around 58cc, my compression is about 10.75 to 1. I have heard a lot about edelbrock heads. this is strictly street driven. I currently have a performer manifold with a 770 avenger carb, headers and true 2 1/2 duals. the car runs great but you allways want more. I wa told it would possibly add 50 to 75 hp, is this true? I know it will help with detonation. I have to run 93 with booster now to stop detonation. what difference does runner length make?

64cc (or higher) chamber heads will bring that 10:75 compression down to pump gas compatability and probably rid you of detonation. Runner length controls flow...too large can drown your engine makeing it difficult to idel/tune well...too small and the motor won't reach potential. That's a simple explaination....I can't get any more technical than that...
Experts will probably chime in and explain more throughly..

I was just quoted on the newest Australian ProComp heads from a speed shop in TN. I had purchased a lite weight starter from him on Ebay and it was a heck of a deal and looks great so asked about a few other items.
This is cut from the email I was sent about the heads:
They will cost around $950.00 fully dressed out, with roller rockers, and stud girdles, stainless valves, etc. They are ready to bolt on. The runners are 200 cc, and the chambers are 64 cc. The valves are 202, 160
I will probably try a set, but have to get them with 72CC as I do not have flat top pistons.
I talked to the guy for a good 1/2 hour on the phone after that. He also builds 383 stroker motors complete for about $3,200 with these heads. He says that they would be a true 410-415 HP.with the components he installs, but I have no other details on the motors.

I would think a set of Edelbrock RPMs or Etec 200s will do nicely and shouldnt run you much more than a grand.
AFR 180s will also be nice if you want to blow like 1300 bucks.

I didn't see anything that says the price is per anything. Each or pair, set whatever.
Just a price per kit which that don't say what a kit is if its a set or pair or an assembled single head.
Oh- the BB heads seem affordable so if they are eachs they want gold in exchange for them.

In reality, BBC afr are ABOUT $1000 MORE per PAIR than a similarly cnc'd & assembled sbc afr. Regardless which brand ... BBC head prices are similarly higher$ than sbc. Just part of why BBC typically cost more to build than sbc.
So ... seems the DELIVERED $ difference between sbc RPM & sbc AFR is that AFR ABOUT Thirty per-cent or $300 more.

I haven't looked at heads for a while (not since ordering both types of head failed to get either delivered
) so maybe the new AFRs are already on sale? If not, trawl the archives for comments on AFR heads before you decide.Measure your ride height at the front with the current heads as the front may lift up slightly if you fit lighter Al ones.
p.s. good luck with whatever you decide - hope you get better luck in actually being able to buy some than I did!
