super commando LP Rockers?

Something I found, probably also listed in the catolog.

p4876310AB COMMANDO LP heads;
Small block performance cylinder head, featuring stock intake bolt pattern for standard manifold, and dual-drilled exhaust pattern for production or W2 exhaust. Utilizes W2/W5 type offset intake rockers allowing unrestricted port cross section from the intake flange to the valve. Intake has an easy flow potential of over 300 cfm with seat and chamber machining and minor porting, making it the best value in small block power potential. Offset rocker allows for the cross sectional area to take power to the next level, far beyond the capabilities of standard layout heads. Compatible with standard intake and exhaust, the Big Port Commando is the low-cost alternative for exotic "race style" heads.
