heads: good flow?
picked up a set of 3932441 (http://www.mortec.com/castnum.htm) heads, ready to rock. they list as '69-'70 with open chamber so i know they can't be as bad as the infamous 882's but anybody know what these heads came on? or can you point me in a direction? just looking for some basic info or even opinion, such as good head, bad head, indifferent, etc.

3932441 1969 350 250/255 bhp 1.94/1.50 76.26
Camaro heads from google...
3932441. This head was found on the 1969-1970 350 engines (255hp 350), it was a decent flowing large chamber head. It had 1.94/1.50" valves, 76CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 61CC's. Not to be confused with 3923441, which was a 1.72/1.50" valve, 327 truck head.

I bought a set of those 9 years ago to put on my 78 4x4. They were rebuilt with stainless valves and the intakes were increased to 2.02. They really helped. If you use flat tops you'll get 9:1.
