Blew a plug today...

[Wichers123]

Average spark plug should be installed hand tight 12-15ftlbs. I have run 20psi multiple times on race gas and didn't have any issues also. I'm thinking of turning up to 25 hopefully in the next month or so.

I always cringe when I see my buddys crank spark plugs tight, especially on aluminum heads..I always use anti sieze and torque mine to 12 ft. lbs.

I went around and retorqued all mine to 13 ft/lbs

Anti seize in aluminum heads are not needed. That mostly for steal heads where corrosion is a big factor. The oil usually dries up and the metallic in it makes it harder to remove plugs. I change a bunch of spark plugs at work monthly and I put them in clean and hand tight.
