JimV did my hp500 heads and I changed cams to pick up some more HP 4mph worth on a 38 foot boat!

SCOTT What cam did you go with after the head work, and how much work was done on the heads?

Stayed with the stock ignition and limiters. I decided the crane 731 would work best for my combo and by the way it runs I would say I made the right choice.
The headwork was done exactly as KAMAA described above with a little removed from the surface to make up for the chamber work and help maintain the stock compression.
