Looks like the exhaust is crossing over the intake seat. All of the research that I've done on this and machine shops that I've talked to said that there has to be a minimum of.030" better the valve's. Is this true?
I‘ve run .020 but that was with 5/16 stems and about as tight of guide clearance as I was uncomfortable with. I was at .0009 and .0011 and that made me wet myself every time I started it the first four or five times.
Then I shat myself the first few dyno pulls. After that I pulled it down, all was good and I put it back together and sent it.
