Which heads would you guys recomend for a 509 with 5-7 pounds of boost, turning max rpm of 5600.
Thanks

Heads need to match the cam for the best performance. It really just depends on what you want and how much you want to spend.

Many choices out there, just make sure they are aluminum.

Best talk to Bob Madera of Marine Kinetics. He can spec heads and a cam that will make more power than you think.

Call Bob at 585-654-8583

Tell him Smitty sent you.

WAY TOO BIG.

The AFR's 315's would probably be a good choice.

I have the same set up. Bored 502efi, procharged at 7#, using the 525 cam and dart Pro1 320 mild port.
The combo dynoed 814+ @ 5500
That was with all the pumps belts and marine exhaust.
