B18 head on B20 block 120-130

The slanting would be fine on all sides but the quench areas (you want tumble there). Insofar as the shape is concerned, a "figure-8" is considered the best chamber shape for two-valve heads with a spark plug in the middle. Of course, realities of construction make that nearly impossible. If there is enough meat in the head without going into the water jacket you will be OK... There may not be that kinda metal to work with.

More likely, you will end up making is less angled and more "dished" in an attempt to get more volume so your static CR isn't astronomical.

Mike!
