I currently just got my block my cylinder head and crank back from the machine shop a while back the cylinder walls were wore 0.010 thousandths of an inch........so we bored it 0.020 over and then the block was honed. They also had to deck the block surface.......and mill the cylinder head 0.016 thousand ths of an inch. Me and my grandpa ordered the piston and rod and rings after we had it in the machine shop. A lot of local pullers say the recommend that specific machine shop. But the question is was it the wrong way of doing the steps. The parts supplier said I should have ordered the piston first to have it taken to the machine shop and bored to fit it. Should I worry about this.
