Getting a set of 63 heads opened up. Not familiar with best practices in Pontiac high performance builds, so I need advice.
Below are options, and another option is aluminum filling on exhaust crossover
Note: with the 7/16" rocker stud conversion you can run PRW stainless rockers with short nuts under the stock 389 valve covers!!
Programs available for 1963/64 #716, 1965 #76,77 1966 #092,093,094
Engine is 421 HO with 716 heads and 859 intake, dual Carters.
So, I need the 7/16 screw in studs. Can someone tell me about the exhaust crossover? Anyone paying attention?
It's all been covered before. Try the archives or the restore tab with all the great info.
It's a shame the archives aren't available. I was going to point a friend to some info the other day....
