Re: LE2/Custom Grind installed...excessive crankcase pressure

If the heads are going to be milled though, teh intake would have to be milled as well, right?

Only milling the heads will drop them lower by that amount in relation to the intake and the intake will sit higher, right?

Milling the intake manifold won't move the bolt holes on the intake manifold closer together. It seems you will have to drill the holes on the intake bigger even if you mill the intake.

I've been messing w/the PCV system, and while doing so, the oil coming from the dipstick is much less. I'm wondering if I'm getting closer to the 6 quarts as more oil continues to splash up and out the tube.

It just so happens that I called Canton's tech line about that very same question today. I have the 15-242T pan and was never sure about the right fill level. The tech guy told me that this pan makes the system capacity 6 quarts total. Fill up the oil filter, and put the remaining 5+ quarts in the pan, and re-mark the dipstick.
