As for vtp like Alan said above .060 .065 exh would be as tight as I've ever ran and it was okay for me. The intake is more forgiving. if I were you I'd advance the cam and get yourself some more exh clearance and less int in my opinion if you are worried about it .

Good luck with it.

Hi Asking these questions I would assume your a newbie to stock. As Alan said did you check it the right way? In my younger years I might have run it with .060 but with the cost of everything today I wouldn't risk it. There are several ways to pick up that little clearance you need. I know it sucks but I would take the heads off and have a good machine shop cut .010 off the back of the valve. If possible move the cam a couple of degree's. What head gasket are you using? Have one custom made .05 larger but tighter on the bore so you don't loose compression. They don't cost that much. Good luck BP

I agree with the above post about giving extra clearance, being on the safe side. I know from recent personal experience flirting with "too close" just cost me about $9,000.00 and set me back a season.
