I have heard of folks doing this in the past, and was wondering if anyone here had done it, or not? I learned tonight that the conventional 14mm thread piston stops available do not work with the GT40P projected reach plug holes.
So I attempted to bust the porcelain out of an old plug, which did not work well. I ended up mangling the plug. Is there a trick to this? Everyone talks about doing it, but there are no specifics for how to bust the porcelain out.
Should I cut it with a cutoff wheel? Drill?
I am going to measure and degree (shooting for a specific ICL) the HO cam I have, and I also want a definitive TDC mark to install the timing tape on my balancer.
Any tips on making the stop?
