I'm thinking of gutting a sparkplug, welding a nut on the backside and using an allthread and jam nut for adjustable length. Any other ideas?

Go as big and strong as possible on the stud. Pistons can generate tons of pushing force when going up to TDC.

That's what I did... works great. Just be careful that it doesn't get in the way of the valves as they go up and down. (might want to remove the rockers if it looks like something may hit)

The porcelain will not come out without a fight. You'll need a hammer and round punch or chisel to crack it up and remove it. after that, drill/thread the plugs bore out to whatever size all-thread fits the best. Use a lock-nut against the top of the plug to keep the 'stop' from moving, and you're in business.

Good Luck!
