super commando LP Rockers?

Why Big Mouth heads?

Advantages of the big mouth head would be;

Light weight aluminum
Moved pushrod like the W's.
Excellent air flow curve.
Standard intake and exhaust bolt patterns. No need for special intake or exhaust patterns. Or adapter plates for headers.
Cheaper headers, intakes, rockers.

W2 advantage;
Higher peak flow (?)
Larger exhaust tube sizes available
48 & 52 degree head for respective degree blocks.
