GT500 exhaust port help needed
Can someone that has a set of GT/500 cylinder heads laying around get some dimensions for me? I need to know the distance from the deck surface to the top & bottom of the exhaust ports.
What I am trying to determine is if I get a set of GT heads if I will be able to install them in an SN-95 using off the shelf long tube headers with the correct exhaust flanges welded on. I do not know how much the port location has been raised (if any) vs. the old B or C heads. They are going on a 4.6 block and I already have the intake sorted.
