The heads have no-lead exhaust seats. The heads are stainless steel shot blasted for a like new appearance, crack checked and pressure tested before shipping. They have our original Pro-Pocket porting along with our custom seat and valve angles and are milled to level the deck. They are fully assembled with springs that are 130# seat and 335# @ .550" lift. They coil bind at .650" lift. The chambers are apporximately 83cc.
The supply is limited so don't expect to see this on our website for long. We did up a few sets of these last fall when things got slow and just now got time to put them on sale.
