AR52's need to be smaller?

Guys I've been finishing up the current motor and put in exhaust studs and now I can't get a spark plug socket on to tighten it up. Is there and thing that has the smaller 5/8 hex plug? Current spark plug is an AR52 autolite

AR3934 may be a place to start.

how much different are they from the 52's

Ok after some searching I have found out the 52's are a few steps hotter plug than the 3934. And I happen to come across the NGK r5671a-8 as the equivalent plug at the local motor cyles shop for $1.55. So I pick them up and will try these in the new motor Lem.

Looks like cold weather and rain this Sunday so no testing for me.

Ace

Yes sir.........the NGK 8 will work too.

OK every things loaded up car has NGK plugs and we will be testing Saturday and Sunday. So Lem I'll let you know how things go as we will UNLEASH the motor and not run the throttle stop.
