Pontiac Cast Iron Cylinder Heads and Labor Prices

BP ports more Pontiac cylinder heads than anyone in the world. After years of extensive R&D both on the flow bench and on our track, we have developed some of the best performing round port and D-port cast iron Pontiac cylinder heads ever. These heads can be ported for optimum performance on a 450 HP street engine or a 700+ HP racing engine, and everything in between. We have ported D-Port heads that run low tens in 3,700 lbs. stock suspension street GTO's to heads that run 8.50's in a 2,400 lbs. bracket car. We also specialize in porting RAII, RAIV, H.O. and S.D. round port heads.

The port work prices include fully ported intake and exhaust ports, deburred chambers, pushrod holes elongated for 1.65 rockers, and removal of excess casting material in oil drain back areas. We can use your heads or we can provide cores. We keep most casting numbers in stock.
(Core charges vary with casting numbers-call for availability.)

A valve job is highly recommended after porting, even if your heads have been recently worked. BP can do port work and a valve job only or return your heads to you complete and ready to bolt on. All BP heads come with a blueprint sheet and flow chart.
