Heads/Cam Compatability Question
Heads/Cam Compatability Question I may not be a newb, but I am by no means a tech, so this may or may not be a stupid question (I really don't know much yet about heads but am slowly learning by reading and then reading some more).
I have a set of Patriot Performance CNC Ported 243's 2.00"/1.55" 62CC heads installed on my 2002 Z28 and am looking to upgrade to a Magic Stick 4 cam (Magic Stick V.4 239/242, .649"/.609" 111 or 112 LSA options). I was told by Gunnar at Patriot that the heads were milled about .015" to get the 62 CC, but my question is will this cam require flycutting because of the milling? (or would it require flycutting anyways?)
Another question: the springs that came with the heads are Patriot Gold Dual Springs good to .650" lift from what I was told. They have been on the car with the current cam (much smaller) for over a year. Will I need to replace these?
Sorry if these are stupid questions, but I just don't know enough yet to make these kinds of decisions. Just looking for some advice and to learn. Thanks!

I think that regardless of the heads being milled or not, you will require flycutting. Check out my thread, virtually the same questions.
