Special offering. Limited quantities. These are completely prepared Studebaker V8 cylinder heads. They are built using the best quality NEW parts from the leading Studebaker parts supplier. They are CNC computer ported from one of the leading precision CNC head porting companies in the USA. The heads all have NEW bronze valve guides, that are machined to accept push on Teflon valve guide seals. The valves are NEW stainless steel R3 valves with stellite tips. They have NEW valve keepers and retainers. Assembled with NEW R2 valve springs. A professionsl 3 angle valve job has been carefully done on each head. The heads have a modified R1/R2 port configuration. The heads are checked for straight and flat surfaces and are surfaced if needed (most are). These heads are the very best quality that could be done to a Studebaker head. Nothing was scrimped on. No shortcuts. The best possible. They are ready to go. Some install information is going to be required, but that is normal on any engine rebuild. Price listed on this ad is for one pair of heads (2 units). The price is an exchange price, which means a pair of decent cleaned used heads will have to be returned to me (so I can continue to offer more quality cylinder heads). If you do not have a pair of echange core heads to return, then an additional charge will be made, as replacement head cores will need to be purchased. Feel free to contact Deep-N-Hock Cylinder Heads via e-mail or this message board for any questions you might have. This is the initial offering on these high quality CNC ported heads. They will definitely up the performance of your Studebaker V8 engine. Pricing is based on the cost of the heads, the cost of the CNC porting procedure, the hand preparation, and the professional valve work and head assembly and machining. A great value for the money.
