Want to run 11.80's in a 3700 lb car?
This is the head you can do it with!
The new KRE Aluminum D port head has the latest developments in cylinder head technology incorporated into it. They feature the standard Pontiac exhaust
arrangement; Saving you lots of money not having to buy a set of round port headers. These heads can be used with stock exhaust manifolds or with standard d-port headers.
The heads are cast from 356-T6 aircraft aluminum and are nearly half the weight of a stock cast iron head. They come with hardened steel
seats, and bronze alloy guides. The deck thickness is 5/8" and they sport a new high
efficiency heart shaped combustion chamber. The spark plug location angle has also been improved
upon to create a very efficient chamber burn.
The heads are designed to use all of your stock D port head parts! (except your head bolts
/ head studs - see recommended installation
items) Intake and exhaust valve centers are in the stock locations as well. These heads were designed for easy iron head replacement. They were also designed to pick up where the stock D ports leave off; Taking you to that next level of performance!
Other improvements....
Oil drain backs are positioned to allow for a more complete draining back of the valve cover area preventing oil from standing on the valve seals
pushrod tubes are designed to accommodate 1.65 rockers without grinding on the heads
ports have a thick roof, wall, and gasket material areas for performance port work
Heads can be used on your 1965 - 1979 Pontiac
motor

Still not convinced that these heads are the right performance choice for you? Consider this....to build a set of Stock Pontiac 6X heads that will flow 240 cfm and net you a pump gas friendly compression ratio you will need to spend about $1,400.00! Off the shelf ready to bolt on aluminum d ports will cost you $1,950.00. Your engine will be able to run better with unleaded gas at a higher compression ratio than stock and be less prone to detonation. Not to mention you will be making MORE POWER!
