alright so im pullling out the helicoils on my s52 block for the head studs, and i was wondering if anyone could get me the thread pitch for these, and also the exterior diameter of the helicoil. i dont know how to find this out before i drill into the block, and it would be nice to have all the pieces waiting to put it back together once i get it out and start working on it.
any ideas about how to get this info myself would also be helpfull
thanks
Ben
