BR, 2.4, high hp/high rpm build?
hold on now i got the undercut headstuds its like the middle man LOL. you can get those. I got them on a good deal from co_o4 awhile back i did not want to use regular one for fear of headlift so i was going to get l19 when i was told about the middle man undercut headstuds.
For my 2.4 build we wanted to make sure we never ran into head problems so we used the Power Enterprise 1.2mm HG (best Head Gasket on the market) and used L19s. For a 2.4 I don't think this should be done any differently if you are going for high boost, high horsepower setup! For a 2.0L you could do a std HG that is cheaper like the AMS ones but for the 2.4L, I didn't cut any cornors!

I also have a question for David or any road course racers out there. I was planning on doing some road coursing for fun and was wondering without oil squirters what if one was to ceramic coat the pistons? Would that give you the same effect since the job of the coating is to solve the problems of wear, heat, friction and corrosion. like swain tech coat the pistons for example. Just curious
I would guess no for several reasons.. first up, tolerances. ceramic coating would mess up piston to wall, skirt to cylinder, etc. clearances.
second, weight. ceramic coating would (even if it fit clearance-wise) require everything to be weighed and balanced again, both as individual setups (cylinder 1, cylinder 2, etc. as well as rotational balance/weighing)
third, even if 1 and 2 worked, ceramic coating keeps heat in/out, depending on application. keeping heat out of the pistons (which would be what your doing) would lead to the heat being transferred to the cylinders (block). the 4g64 already has thinner cylinder to cylinder clearances, from what im told (which is why many dont push them out so far rpm wise). heat away from the pistons is good, but it has to go somewhere (in the 4g63 land, to the oil via squirters)

Ceramic coating is a heat barrier. So it would be good on top side of piston to sheild it from combustion temp. On bottom side it would be bad. The bottom needs to shed as much heat as possible. From what I have seen ceramic coated piston tops are like snake oil. It works but from What I have seen it doesnt stay on. combustion chamber is too violent. okay for drag car but on a streett car it will burn off after a few thousand miles.

Rockmanx - energy isnt created or destroyed. heat has to go somewhere. all "cooling" is, is the diffusion of heat. by ceramic coating something, you arent making heat disappear, your causing it to go somewhere where it is more easily absorbed.
i asked about it and he told me so i think I know whats up me and this guy ^ are on the same page..
