Plug read, opinions needed

That actually makes sense when you look at the chamber shape and how close the plug is to the valves. A projection tip is going to be right in the edge of the flow path. I don’t recall seeing if you had mentioned what cylinder head that is, but it looks plenty trick.

Not in this thread but I started a thread a few months back about setting up installed hight and how close guys strive for perfect while I was setting these up. There’s a lot of pictures and measurements in that thread. These are 360cc, CNC ported pro max BBC Chinese heads that my machinist did guide work, a new valve job, installed Manley severe duty inconel exhaust valves, and stainless intakes in. The chambers are all cnc cut and measured 120-121cc on all 8. They were a lot of work ($$$) to get where they are.
