Gx series compatibility with non-hemi predator question

[Smerft85]

I have a good running 212 predator, and several gx160 hondas with the wrong shafts so they are donors. Could I use any gx160 parts to beef up rpm or anything in the predator? I know all the tin matches along with carbs and exhausts, but would a 160 head on a 212 be an improvement, or is it a lost cause trying to Frankenstein something worthwhile?

All you have to do is measure your valve sizes and compression height.

I had read a 160 head on the hemi predator was a huge compression gain, so in theory it should work fine in the non-hemi and still give higher compression, but I don't have either apart at the moment to measure anything quite yet. Was thinking the flywheel may be different weights between the two and maybe that could make a difference somehow too?

I'm pretty new to small engines, I only know enough to get me in trouble, perhaps I'll find a non-running 212 to experiment with and use my running one as it is.
