maybe that is what bent the valve i over revved it with about 65-70 psi of boost

View attachment 71805 you can see where the valve contacted the piston, but the piston is still okay

turns out, i bent all of the ex valves and only one intake, the guides are still good, just going to port the ex side and blend the bowls with some valve angle work, go with all new valves and seals, f-1 springs, and since the head is off, i will go back on with Lmills evil twin cp-3s:-laf

Factory springs cannot overcome 50+... ... Ouch.



At least, you will be prepared from now on.



Thanks for the pics, keeps reminding us how close to the edge we are.
