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!
