You need to check your PTV clearance regardless. Head gasket thickness, milling, cam. Lots of factors come into play before you can say for sure. You need to be checking your pushrod length when youre doing this stuff as well!

You can cut .050" from the heads, they are fine with that much cut. MY L92 VicJr bolted on with no alignment issues - port alignment was still decent(I cleaned mine up a bit). I think that .050" is pretty close to as far as you can go and still have alignment good(with the VicJr).

I will back it up when my engine goes on the dyno in Feb

Sent my heads out to Rick Crawford to get the work done. I should have them back in a week or so. He doing a clean up on the intake side, Heavy exhaust porting, reshaping valves, valve job, and a .050" mill. Here I come 500 wheel.

Are you going to get them flowed as well to match your cam? I would assume if you open that exhaust up a bit you can get closer on the split of the cam.

dont worry about cam split, let a cam specialist design you a cam. Besides more exhaust duration will help it RPM, and there is POWER in RPM
You will hit 500 rwhp
