Not sure on the spark plug size, the heads are still @ the machine shop right now.

I hope to be going by there any day now to drop off a set of pistons so they can get my block work done, and I'll check the plug machining then. I'll grab the dates also.

(I can't wait to hear this thing make noise on the dyno

)
