I'm Awesome
Yeah, the idea is to run cooler to try and avoid detonation. Pretty easy to swap out later if the datalogs look good. Not sure my cam is wild enough to compensate for the increased CR. Also, im pretty sure the heads were milled .020 to clean some damage when they were rebuild. Lost the paperwork....
Shurkey the calculation I used didn't account for the top ring height but the rest of the numbers look spot on.
I am only running a cam that specs out with the 1.7 rockers at
272/284 @ 0.06,
218/228 @ .050,
.578/.578" lift,
110 LSA and 106 ICL.
Running 170°F it runs all day on 87 at 34° total advance above 3,600.
