OK, still looking at Ol' Red getting a new heart- Got a 4 bolt block being bored and line honed, so that part is done. Found a 496 forged rotating assembly, so that's pretty well done too.
Now looking at heads-
AFR, Brodix, Dart, and RHS are all very pricey and advertise having "open" combustion chambers. The difference is pretty visible looking at open and closed side by side.
What's the advantage to open over closed, other than in the upper RPM numbers??
Anyone ever played with the difference? I know you can put open chamber heads over closed chamber pistons, but you can't go the other way without making lots of very small pieces that you can't use anymore.
