At this time, the waiting list for cylinder heads has grown to the point we will no longer add to it.  We are working with the foundry to finalize when the next batch will be ready. 

This is a listing for information only regarding the alloy cylinder head. UPDATE:  The price for this package will be $2250 plus shipping.  The increase is due to an increase in the price of castings and Dual Springs are now standard, as are 1.84" intake valves.  Includes: Assembled aluminum cylinder head (dual springs, retainers, and viton seals), alloy intake manifold, and carb adaptor. Also includes stainless steel hardware for installing the manifold.  Custom porting or other machine work is available. If chosen, this will lengthen the delivery time.
