Cylinder Head
Services
Butler Performance
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 800+ 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. We can do port work and a valve job
only or return your heads to you complete and ready to bolt
on. All Butler Performance heads come with a blueprint sheet
and flow chart.
Many
of the prices listed below may be included in a complete head
rebuild package price

Edelbrock
Aluminum Heads
Edelbrock
Performer RPM heads produce outstanding horsepower with excellent
low speed torque and throttle response. Designed for 1965-79
389-455 c.i.d. Pontiac engines, these heads are patterned after
the 1969 -70 Ram Air IV Pontiac cylinder head. Two styles are
available: a street legal 87cc combustion chamber version for
low compression applications using 92 actane fuel and a 72cc
chamber version for higher compression, racing applications.
Both heads have Ram Air IV exhaust port flanges.
BP
has conducted extensive flow bench, dyno, and track testing
with these heads, all resulting in great performance numbers.
We have cylinder head packages for any application, from 6&7-second
racecars to 8 & 9 second street cars and even daily drivers.
Call for a cylinder head combo to fit your needs.
All
BPI heads have polished chambers and the pushrod holes are slotted
for 1.65 rockers, included in the prices.
All BPI Edelbrock in-stock heads can be
upgraded with roller springs, titanium retainers, milling, o-ringed,
etc. for additional price. Or, you
may send your Edelbrock heads to BPI to be ported and upgraded
for improved performance. Call or email for a detailed estimate.
