Im putting together a 370 built for alky the piston seems to be .019-.020 below deck height at tdc and the head has about the same at the edge of the squish band I am using sodder about .070 thick and its barely touching when I rotate I've checked squish before but its not making sense i was also using a .020 base gasket but it wasn't even touching at .070 so I took it off and that's when I got it to touch the sodder any ideas?
