Don't go the rectangles unless you plan on getting some massive HP and RPM's out of it. If you want aftermarket heads I'd go for the Brodix aluminum oval ports. They are a 255cc intake runner, so they are perfect for a smallish big block chevy. I'd get them with the 2.19 intake valves NOT the 2.25's. The 2.25's will not clear the valve notches in the pistons. The Edelbrock performer RPM heads are another option, 290cc oval port, a little on the big side but have a smaller 110cc chamber so they will be better for compression. I'd shoot for around 9-9.5 to 1. What kind of heads do you have right now? What #'s on the heads?Last edited by 69elko; 01-28-2007 at 06:46 PM.
