- Our heads are all shipped with installation tips, a sheet of desired clearances for setting up your engine, and a flow chart from your head.
- Super Alloy valves are a hybrid incoloy that are 5 times the tensile strength of an inconel valve, less weight, and have better heat management properties. These valves have memory to return to their original shape as they cool.
- PAC Enhanced valve springs are made in the USA and have gone through anti-fatigue processes for longer life and better valve control than the competition.
All heads require a core! You can send us your head, or purchase one from us at the current market price.
