I'm pointing out that the ground strap could be exposed to far more heat in that location than if further from it. It can point to the exhaust I dont see that in itself an issue. I just think if the plug and ground strap are closer to the intake valve the ground strap will get cooled some by the cooler charge near it.
So... which would be more likely to get the ground strap glowing? Cooled some by fresh intake charge in close vicinity? Or have the ground strap exposed to the higher temps in the vicinity of the exhaust charge?
Plenty of good heads out there with plug pointing toward exhaust but I dont recall seeing any with the possibility of putting the ground strap too far into the exhaust path.
But hey, I havent been approved to be knowledgeable on matters of preignition. So if you want to ignore it, who am I to stop you? Never said my opinion was expert merely making comparison to other good heads including some raw pro stock stuff out there.
Sorry I've noticed something!
As they appear in these pics it seems a tid closer than you might want it.
So... maybe a picture of the chamber with the correct reach plug and an exhaust seat and valve in it might clarify this better. Espeacially better clarification if a chamber gets roughed in more.
