about 200 cfm of flow at 25" of water for a pressure. I can port any head, and usually have enough in
stock to do an exchange basis. If you do not have a head I can get it or already have it and can start to
work on it immediately. I do charge a core charge for heads. There are basically 3 types of port jobs.
There is a stage 1, stage 2, and stage 3. Here is the breakdown information:
Stage 1: A stage one head is for those that want a bump up for a modified street car and are planning on
adding a cam with such values as .470" lift and 260-270 duration. With this sort of cam and this head
you will have a good 7000 rpm band range if you have the proper induction. This would work well with
a stock FI intake.
Stage 2: This is for the weekend racer/street car that wants to have allot of upper power up to about
7700 if went up with like a 270-290 duration cam and about .480"-.500" of lift. This head would work
great with triples, and SU's, but might be too much for a stock FI intake.
Stage 3: The stage 3 is for the "all out-go getter". This head is the one of the graphs shown. It will work
with up to 300+ duration with up to.650" lift. This head will work well with all applications but requires
after market induction system to get it's full potential.
