Hey guys, I really need the cross section picture picture of a 4.7 head between the valves across the squish section. I'm going to try out the Singh groove and dyno before and after to see if it really helps on our engines. I have 215K on the engine now and it just started leaking a slight amount of combustion gas into the coolant,(long story, but involves rebar through the radiator). Now I'm changing the head gaskets and figure why the heck not since if it doesn't work I have a new HO complete engine on the stand in the shop! I don't want to cut too deep on these and ruin the test before it starts, but if it works its well worth the work. Thanks guys...Dan

Well I've tried Travis several times and never got an answer, so again, does anyone else have a cross section of the heads?
