225 /6's created equal?

Don't think there were many mods suggested for the heads other than milling for compression and general blueprinting.

By whom? The #1 mod I've heard suggested for any SERIOUS slant is major port work done by someone with slant experience.

Most of the emphasis for extracting performance was raising compression, hotter camshaft, the 4bbl intake and exhaust work. The usual mods for any engine.

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.
