Studs torqued to 90lb-ft deflect the bore the same as OEM bolts torqued to 90lb-ft. Same as close as I can measure anyway. Pulls the bore about .0015-.002 on diameter or .00075-.001 under each fastener. I thought it was more because there is about .001 taper in the bore from the last build. I torqued the studs to 80lb-ft and the next step will be to hone. I think I can get the bores round or nearly so at 3.937 top and 3.936 bottom. Pistons are 3.932. JE specs .004 minimum clearance for these pistons so I'm in good shape.
