I hear the spec 5's wont work with the ctr's. Is that true?
Hope you dont plan on running pump gas in that thing

Your almost 13:1, dont do it, sell the CTR pistons an use PR3 (B16) which will give you a nice 11.5:1.

BC5s are too aggressive for that setup, youd be better off with Skunk2 PRO1s are BC4s
