360 head trip

I was looking at stone setups today...

Gonna drop a head at the shop today, can't decide if I want to also have a nail head cut down to the same seat so I can switch them-tulip back cut against nail head back cut.
I dont know....they are gonna want to do guides as well...

back to looking at stone setups..

have one cut and do some testing with it. if it's a good thing, now's the time to do it.
before the guide are set to the used valve stem.........................

Check EVEL bay, a good deal will come alone..........buy it all new:sad5: scary!!!!
the stone set up that is!
