way over my head
i bought this block last year for a build, it had just had a liner in number 4 and had 6 long studs machined out so it is ready to rock and roll

only think is im doing somthing diffrent now so i dont need this Block and i want to sell it
got someone very intrested and they have asked what the bore is as if it is only 0.5 then that is cool but if it is 1 over then it is no good to them
every one of the bores were the same not just the one in the pick and if 90.810 TO 90.820 is standard i would say that my blocks pretty bang on and not over the 0.5 that the guy is worried about wouldnt you say?
