Anyone know if there is a version for the larger thread as I have a 35 engine
with Aluminum heads.

You probably have to use 18mm to 14mm adapters and then find the correct 14mm plug with the correct reach.

I looked online for a couple hours this morning for that spark plug comparison I mentioned in my 2nd post on this thread. I was not able to find it. I know what I read though because it didn't have E3's blessing and was impartial. I've been reading stuff on snake-oil long enough that I lumped what I saw in that test into the "entirely plausible" category rather than immediately dismissing it..... as is the normal conclusion of 99.95% of aftermarket stuff that is hyped.

I don't know about on completely factory engines, but with ignition stuff, the farther from stock and the more radical the equipment is, the farther down the
rabbit hole you need to go to extract performance..... usually at point on the graph well beyond what the original engineers intended from the engine.
