225 /6's created equal?

Cam, headers and 4bbl will have a minimal effect until you do something about the slant's port flow, which was designed for a 170 cube engine.

I dunno. Mike J is running in the 14's with a 2bbl Slant and a box stock head in his Diplomat.

I bolted a 390 Holley and Clifford headers on a stock long block and went faster than a lot of the guys with ported heads.

You are right though, good headwork is the key to making big power.
