no, im running flat top pistons( JE) -5cc. i have not posted in Gen IV cause i always get better assistance in the drag racing section with all of my questions. I think you may have a point with the new sparkplug location in the TFS heads. I guess i will just have to stick with the old copper BR7EF plugs

Odd. NGks are usually the easiest plug to thread in. If they are tight, you should see how bad an autolite is. Worst yet, be terrified of a champion. Just my experience.
