440 source heads on a stock 440

I don't cut anything off the intake. You have to elongate the intake bolt holes a small amount, but you cut nothing off of it.

This makes the intake sit higher up on the heads because the deck height is now lower.

There is always a misalignment were in the port roofs of the intake with most all combinations even if you port match,

your still not getting a nice straight transitionless roof.


Doing what I am talking about allows you to straighten the ports in the head and the intake out and have a very straight

smooth roof instead of being curved down like intakes and heads are at the opening. It takes some time and effort, but by

doing what I do I can get a 9.5 to 10 compression short block using stock pistons that were way down the hole to start with.

I have been building engines and racing for 36 years, so I have learned a thing or two about how to make power.

This might sound like a unorthodox or foreign idea to most people, but if you really understand how to get a lot out of an engine

then you will understand the logic in what I am talking about.
