This is what happens to stock motor with comp 278's

I would absolutely degree those cams...even with the flycut. Degreeing your cams does two things: 1. ensures proper clearance and timing and 2. optimizes valve timing to provide maximum power gains.

If you don't bother degreeing cams, you are rolling the dice. You may get lucky and the PTV, etc will be fine. You may end up right back at square one where you began. Do it right this time and degree those cams! That way you know you are getting the maximum performance out of your investment too.

my two cents...

Degreeing your cams only places the timing events correctly. You still should check PTV

Thanks for the info. Diff check for ptv when I rebuild motor once I get my pistons and heads back from machine shop.
