Trying to improve on the best factory small-block cylinder heads ever built is no small endeavor. And yes, GM’s 12-degree LS7 castings are the best small-block heads of all time-regardless of engine make-trumping even the legendary Ford Cleveland heads. With a full CNC rubdown, monster 2.20/1.61-inch valves, and raised 270cc intake ports to go along with a flat 12-degree valve angle, factory LS7 heads flow 360 cfm out of the box. That’s big-block territory, and at a hair less than $3,000 for a set of fully assembled LS7 heads from your friendly GMPP distributor, they’re an exceptional value as well. So naturally, we were quite intrigued when Mast Motorsports announced it had just developed its own 265cc LS7 castings that outflows the factory design in a smaller bore.

LS7 performance for your LS3 LS2 or other 4.000″ or larger bore LS engine! Ideal on stroked engines, this LS7 265 head was designed from the ground up.
