I would start at autolite 3924 and experiment if you like

 

oh yea, good ole cheap copper autolite 3924's. do the .054 gap if u got NO power adder.

 

+1 on the autolite 3924's.

You can also use ngk fr5's, but to be honest, I had the fr5's in my car before, replaced them with autolites which are cheaper, and it runs great with them.

 

Ok guys thanks time to get some 3924's

 

I like the Autolite XP24's which is the same plug as the 3924 but its a iridium...

 

I run the autolite racing 3924 plugs on my heads.
