I'm looking at a set of milled heads(to 63cc) How large of a cam can I go with before I have to worry about piston to valve clearance?
thanks

W/ a cut of .030", you should be able to use a cam w/ .550" lift. I have done this w/ no probs. Unfortunately, I do not know the formula for computing the p/v clearance precisely.

I think you can go bigger than but also not sure how to calculate exactly - and duration and lsa comes into play as well. for example for my LS1 .030" I was 'ok'ed to run a 226/226 .575 on 114 lsa by a reputable tuner sight unseen. I'm sure you could go somewhat bigger than that, that is still smallish by today's standards.

Any one? How much did you mill your heads before you had to have the pistons cut??

TTT. I am curious if anyone can give a definitive answer as well!

Yes I have been looking at the TEA 5.3 heads milled .30.
I was under the impression that my "small" .566 lift cam would fit no problemo.
What is the lift on the TR 224 ? I did not think you have to flycut to run that w/ milled heads.
Also if anyone knows what is the desired octane with such a set up ?
