2019 summer race.... Jadaharabi vs 318willrun
Both stock - Magnum vs 360 "596"
Wow is there a difference in the bowl area. Unbelievable. And to me, the bowl is one of the most critical parts of head flow. Also, the valve stems are obviously way smaller on the magnum, allowing even more bowl area. I also like the exhaust ports on the magnum, but not overly crazy on the intake port. In fact, I like the intake port better on the LA head.
Anyways, I don't think I'll really do any porting on the magnum heads, I think I will "clean up" a little on the castings, and take the push rod "obstruction" (I'll call it) down a tad.
exhaust 24 mm socket fell into the mag, no way to enter the 596.
intake 30 mm socket would hardly make enterance on the 596, but fell into the mag with slop
Snap shot of the obvious valve stem size difference
Even with these poor quality pictures, you can see the difference in the bowl area (sorry, my wife had the good camera)
