Hi all,

I am wondering what sparkplugs you all are running. I have a mild 350 with a set of headers from Summit racing in my 67 GMC. Problem is 2 or 3 of the sparkplugs are too tight to the header once I put the boot on...the boot actually touched the header. I do not want to dimple the header so I guess I need to run shorty style plugs unless someone has had this issue in the past and would like to lend a little insight.

Thanks all!

Erik
