Hello everyone,
Just wonder if the modifications that Tri State Cylinder head has made to the gt40p heads would help or hurt a stock motor in terms of 1) drivability, 2) performance. I spoke to a rep. and he said that the larger valves allow the head to breath better. He also said that the heads are milled between 3 and 5 thousands. I asked if that would create allignment problems to the intake manifold and he said no. Was he correct? The specs are as follows:
Ford GT40P Remanufactured
289/302/
60cc Combustion Chamber
Pedastall Type Rockers Used
Positive Oil Control Seals
5 Angle Valve Job
Stainless 1 Piece Swirl-Polished Under-Cut Stems 1.940” Intake Valves
Stainless 1 Piece Swirl-Polished Under-Cut Stems 1.540” Exhaust Valves
AWSF-32C Spark Plug
Springs Good to .550” Lift, (Hyd. Roller) *check cam manufactures specs for compatibility*
(129 psi @ 1.800” / 280 psi @ 1.300”)
100% Satisfaction Guaranteed!
They are $598.00 a pair. What do you think? Opinions please.
