Has anyone used these head bolts.
I was talking to a tuner at a local car show a few weeks ago who says he dosnt use long studding on his engine builds unless there is a crack in the block.
He said he gets his headbolts made and when describing the bolts I think it may be these so was wondering if anyone has had any dealings with these.

Cheers
