6 bolt arp bolts on a 7 bolt...

ok,may be a dumb question but:

Ive got arp head,rod & main bolts bought for a 6 bolt.

Will these work on a 7 bolt?

The rod bolts no unless your using 6 bolt rods, head bolts wont unless your drill and tap your block, the mains will also work.

so the head bolts are bigger maybe?

I didn't think the rods would because the 6 bolts have bigger rods?

Yes the 6 bolt head studs are 12mm and the 7 bolts are 11mm if I remenber correctly.
