Mr caped engine builder,
This is not the first car that has had issues with lack of cooling in the head sadly. The Mustang comes to mind.
Started back with the 03/04 Mustang cobra four valve cylinder heads (the Mach one also had these heads, but no supercharger to aggravate the problem more). Basically, cylinder 7&8 would fail because of a problem with a "heat pocket" in the cylinder heads. This heat would cause premature valve guide wear and in some cases, cylinder failure. This was "fixed" (created by forum members and venders mind you, not Ford) by pulling the freeze plug out and creating a direct rout back to the radiator, through a metal fitting mounted in the head and a hose running straight to the upper radiator hose just before the radiator. Having a very tight piston ring to wall clearance didn't help either.
Fast forward to the new mustangs and some are still having this issue. cylinder 8 keeps failing. So far, to my knowledge there hasn't been a single failure of cylinder 7&8 on cars that have installed this "head cooling mod," although, I haven't paid too close of attention since I bought the FRS.
If this is a heat issue, there is no reason why a revised head wouldn't help fix the issue, of course, like @
regal pointed out, this depends on the routing of the cooling passeges on whether or not this is even a viable option. Since I have no idea what the passeges look like, I have no idea on it being a true solution.
