ok since i'm building a N/A allmotor the question stand should i machine my valve relife pockets on my pm7 pistions?" i was watching this video on a 200whp b motor done by omniman(good video to own. :TU:) he stated you should do this if you're shaving you head and running hi-compression. i'm not going to shave me head(not that it won't happen in the future) but the question remains. but the reason i ask since i will be putting in some itb's and ajusting the timing will come to play on later. he stated if you're going to do this that, these are the safe # for doing it:

drag pocket - .020"
plung pocket - .015"

thanks
