I just ran this through PipeMax (had to guess on LSA and ICL, went with 110° just as a WAG), it showed 108% v.e. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

That's a lot of meat to take out of those heads--I don't envy you there. (I can almost smell the cast iron!)

Have you ever tried a 2.055&quot; with a relief at the top of the bore? I wanted to try this on my 302, but it's so hard to keep compression in these tiny engines, I didn't want to cut that big of a relief in the chamber and on the block. I probably would've lost close to a full point of compression.

Again, that's a kick-ass little build you've got there. Can't wait to see what it runs. [img]<<GRAEMLIN_URL>>/[/img]

1.5 1.5 3MM Naper and Low oil.
108-108
I did a test on relieving the bores many moons ago on a hot motor on the dyno with a Air flow 220 205 heads. No other change. I saw about 3HP.
