so i keep reading about the oil/vacuum pump bushing can fall out in the hot tank. i didnt notice it before and dont know if it has fallen out, what does it look like and where is it?also, when measuring the piston protrusion if i am doing it right i am getting .025" on all cylinders. the spec in the Bentley book shows .026"-.030" for number one notch head gasket. does my measurement of .025" sound right?and i am thinking of using a stock head gasket with arp studs i reckon ill be ok with that just keep an eye on the gauges.any pointers will be helpful
