Rustolium silver paint works great for this. The factory recomended it for a replacement to raise compression. I used it on my 165 and it has lasted for 3 years.
Pulled the head on my rebuilt 63 175 to check whether the rebuild had a proper shorter jug as it was changed to 165 flywheels...domed piston outer edge appears very close, within 1/16" of top of cylinder, so guess it is OK; anyway, there was no head there a liquid substitute used, maybe to increase compression?
