Yeah it gets hot quick, but my pump is benched to 532cc @ 25* timing, with SDX comp DVs, 5k GSK, rack plug, with no plate at the moment. I at first had a 5" exhaust going to a 7" stack but ditched that for 4" straight piped duals. When I switched my exhaust systems the temp didn't jump up or anything.

But the HT3B with the hx35 is a good compound setup. We have a couple guys in our local forum running those compounds and they are putting down mid 600s on the dyno and are pretty much smoke free

you can pull your old head bolts out and go down to copper state or a good local hardware store and match them up, idk if home depot or lowes would have them, there are 3 different size bolts that hold your head down, there are also a few different washers you have to use to work with the valve covers and i had to grind some of the webbing out of the tops of my covers to work with the allen bolts
