Stan, could you temporarily epoxy a couple of bolt holes and then drill them back out when you are done?
I could, but he made it clear he was done.
It was just a science experiment anyway.
Just to find out where I was.
It will be what it is.
Last pass it was pulling hard all the way into the rev limiter when I missed 3rd gear.
Maybe on the other head I am working on, I will get it flowed.
That one is getting the 11/32 stems with bronze walls and some guide trimming.
I spent a rainy data plotting all the numbers I could find on the interweb in excel.
All the plots I saw the intake ports fall off around .3 to .35 lift.
All were 100 CFM less than an aftermarket Aluminum LA head.
