Im just curious which is better quality for a longer lasting and powerful motor Dome type pistons or shaving the heads?

 

In both cases you are raising compression...in both cases you are also going to need to check your piston to valve clearance .080 intake and .100 exhaust. The head gasket should be selected after measurements are taken. There are many things to consider, I would advise reading this for starters http://www.carcraft.com/techarticles...tio/index.html
