What are you building, small block or a big block

 

[TURNA]

Most likely a 350 or 403

You could put BBO heads on but you would need to mill heads for compression. What kind of power are looking at

 

[TURNA]

Just a cruiser

If this just a cruiser, I would recommend number 5 , 6, or 7 olds heads stock or a little porting with a nice cam with flat top pistons and a performer intake and call it a day. Pro comp heads for a cruiser save your money and use it for something else like a roller cam.

 

[TURNA]

got that already

my cruisers are 11 second cars


I wouldn't mind a set of 5As I would buy them if someone had them
