im looking at a going a different route with the engine since i lost a cylinder in mine. I want to still be able to run my headers and my switchable exhaust. looking going back to a carb motor but the motor im looking at is running a large solid lifter cam instead of hyd. and needs to run dry exhaust so I want to change the cam out so i can run my exhaust

Jim runs a real mild cam on his 780HP 565. 230/236.
He can spec a cam. With those heads the lift is important.
I think the same cam he uses would be great in that engine.
I would run those solid Isky's on his hyd roller like I do. Lash them to 0.006"-0.007" and hold on.
They were sent out to Isky and rebuilt .
He can also order the cam for you.
It was a beautiful weekend out in GH so get at it! It won't last

Cam choice will depend on many other factors. It depends on the cubic inches of the engine and head flow.
A cam that causes reversion in a 454 won't necessarily revert water in a 502.
