i orders gsr arp studs for lsvtec conversion with gsr head.
3 center stud on the intake side are much higher than all the other ones.
i googled pictures and found that all studs are leveled.
wrong studs? or is this correct?
hard to see but it looks like the studs are too far up that i'll run out of tread before bottoming out before the nut will reach the head.

 

all the studs should be the same size. if you have 2 longer than the other, you got ls head studs.

you might have debris in the holes.
