440 source heads on a stock 440

In the hole is never a good thing. Take the engine apart and have the block decked so the pistons are within .020" of the deck.

I have done this many times, to many 440's. The last one I did I cut the block .110" and keep the piston .020" in the hole.

This will wake up the engine and it allows the intake to sit higher up on the heads, so the roof on the cylinder heads can be raised a

little and gives a real nice alignment with the intake port roof. This modification really makes a stock short block come alive.
