Uh oh, power steering bolt broke into number one cylinder?

Measured a 340, 360 and 3 318's. from the block face inwards to the cylinder the 318's averaged 654 thou. the 360 was 647 thou and the 340 was 623 thou. Add the front cover and gasket thickness to this (458 thou) and that bolt better have an under head length of less than 1.1 inch. Not allowing for washers or P/S bracket.

Nice depth gauge. Anyone building a engine should always check the depth of every hole. Just to make sure the bolt tightens the part before bottoming in the hole. head bolts are also critical. you never know if there is an obstruction in the hole. My son has me go over every hole on an engine with thread chasers then blow them out with brake clean and air. You never know whats hiding in there.
