AF-3 or ASF-3 if you can find them. They are what I always used in dome piston Clevelands.

Although Alex has spoken, and he has a ton more knowledge than I will ever have, I always had pretty good luck with NGK's in my domed clevelands on the street. Now I have AR133's in this motor (not enough clearance between the plug and the piston to run anything else, and I still have to run index washers to make them clear.) But, I would run what Alex suggested, he's never steered me wrong.I would think your motor would really like a strip dominator intake.

I just never had any luck with NGK stuff Rob. Not in cars, bikes, or even lawn mowers.
Their heat racnge interchanges are so far off of everyone elses it's almost as if they intend on customers missfiring, that try to switch brands.  ------------------

I must be lucky. Until I switched to the Autolites all I ran was NGK's in both my race and street motors. And I never had any problems with them. Their heat ranges are listed backwards (a -8 is colder than a -7) from everyone else, and that is kind of a pain. I have acutally took plugs that I had pulled out of a motor and threw in a pile and used them a year or more later without any problems (when in a bind).  The only plugs I ever had any problems with were Champions, and I now refuse to ever use them in any thing ever again.

I always like the AF2 in a good running high compression cleveland with pop-up's on racing gas. With flat tops and racing gas, the AF22's might be a little cold but AF32's always ran good.

I use the 22's with BIG cylinder pressure when room allows. ------------------

Thanks for the plug advice guys. Also Kid V, I am keeping an eye out for a strip D. Maybe a July birthday present.
