NEW CHEV BB ALUMINIUM COMPLETE CYLINDER HEADS

BIG BLOCK CHEV ALUMINIUM CYLINDER HEADS
755+ HP OUT OF THE BOX
THIS PRICE IS FOR THE PAIR

This Offer is for a pair of Procomp Pro Series COMPLETE aluminum cylinder heads
Heads will suit all BB Chev including strokers motors
These are the perfect street/strip heads for your small block Chev, perfectly balanced heads for a street/strip engine.
Not too big where there is no low end torque and not too small where the engine will make no top end power.
Procomp heads are pressure cast instead of sand cast like most cylinder heads are made. (Including Edelbrock)
Pressure casting in turn makes a much stronger, symmetrical, and less porous casting.
Everything else being equal a pressure cast head out of the box will outflow a sand cast head.
heas are ready to be bolted no extra work required.
