If they are milled to 59cc,NO.If the chambers are welded and machined to 59cc they should work since they wouldn't have lost any p to v clearance from the stock castings.

I'll be using stock GM head gaskets.

If you put 2.00/1.55 valves in there then it will fit if heads unmilled.

Similar don't mean squat anyways. Duration and valve events is what determine if a cam will fit certain heads.
EXPL: 64 cc 5.3L, unmilled with stock gasket (2.04 int/1.57ext)
232/234 112 will not fit but 232/234 113+0 will
