I pulled off the high head on my 1912 engine today and i noticed the engine is fitted with fully domed piston heads .
The domed pistons run approx 1/2 inch above the block deck. If i was to change to a low head could it become a mechanical catastrophe ?
Can i run low head using domed pistons

Re: Can i run low head using domed pistons
I just found this in the 2009 forum..

I asked this same question a while back. 99% of the responders reccomended the stock (flat) pistons and then go with the high comp. head. You can not install a H.C. head with domed pistons.
I went this route, and I'm happy that I did.

Re: Can i run low head using domed pistons
I run the high dome pistons with a low head on my 13. No problem and hand crank it.
BUT when building it, trial fit with no head gasket (and perhaps some plasticine on the potential “pinch points”) just to be sure of no “interference”!!
