I'm running a flathead 8BA with aluminum Edelbrock heads. I am wondering what sparkplug might be the best choice for this set up. I[ve been told that the champion #271RC12YC would work but Im also running an Isky Max 1 cam and dual Stromberg 97s. Any input? Thanks.

I was told by Jim @ Reds Headers to use NGK-FR4GP with my Edelbrock heads.I believe that they are an extended reach plug due to the thickness of the head

Here is the thread about spark plugs for Offy heads (which should be similar to the Edelbrocks). In that case, I use Autolite 437's.

I also use Autolite 437's in the Offy heads on our '47 and Autolite 216's on the stock heads.
