Default Valve clearance question.

Just want to make sure there won't be any issues. I have a Forged 347 with Patriot 243's. They have 2.02/1.60 valves and are milled .030. The cam I am looking at is a Comp Custom Grind, 236/248 .601/.615. What are your thoughts on PTV clearance issues? If any.

Thanks!

LSA? I'd think that cam, with those heads, would be close. Too close...

Do your forged piston have valve reliefs in them? You might be okay but, a 236/248 on a 110 with .030 mill sounds dicey to me. I'd measure it if I were you.

haha all the **** you gave me for suggesting donkey dick cams for the past 2 years and look at you now...

i think that cam would work with those heads and a -2cc piston, but there is only one way to know for sure. check it.
