454 head choice
i have 454 that i am rebuilding for a 72 chevelle that will be set up mostly for the street but will see the strip some. i am in the planning stages right now and while shopping for parts i came across a set of gm performance heads, part number 12363390. i was wondering if these are a good set for my project. i am planning on boring it at least .30 over maybe .60 and a compression ratio about 10.5. i am not for sure about a cam yet but due to my budget it will probably not be a roller. any suggestions here would be welcome also. i am shoting for 500+ hp. the car currently has a th400 with a 3000 stall. ford nine with two sets of gears 1) 5.00 with a spool (for the strip) 2) 3.50 posi (for the street) thanks for the help.
