587 heads, legal stockers, 3 angle valve grind, sanded seats, and back cut intake valves sanded to smooth radius, mopar, sst valves,1.88 valves,test at 25 " 211 cfm, 122% port velocity . just food for thought. i don't know how to post pics here.
587 castings.
They came 1.88 and open chamber.
The 4th 75 cut would help, but it's not required in that example. 3 angle is great for everything that came with the valve size being used. The factory already cut the 75 and sometimes another 90.
That's not bad, the lower lifts are what I'm curious to see, they vary a lot in terms if peaks. I've had some peak anywhere from 199-208 or so. I'd have to look.
