Can mill them too much, Can go big boy cam, hard to get good compression numbers (11+) for a solid combo, thus can't really tap into the huge flow numbers anyways. |
they dont need a big cam to run, just the right cam. ive got a stock bottom lq4 and the l92s made it wake the hell up. its night and day difference between these and the 317s.
