Head stud goes into block too far.

I have an ls2 im doing heads on and my builder used studs on the two shorter bolts on each head. I ordered a new set of bolts and they didnt have the short ones so i have to reuse the studs.

For some reason, one of them screws in the block too far. I cant get enough thread for my nut.

It seems to go in hand tight to the right height, but once i screw the nut, it threads the stud in farther. Is there anything I can do? I want to get this car running asap and I dont want to have to buy two new head bolt sets.

Only thing i can think of is maybe putting oil in the block threads to hope it wont keep screwing in or possibly use a thinner washer (grade 8 from hardware store).

You shouldn't mix fastner types on a head install. Order the proper bolt kit or stud kit.
