Solutions for too much compression

My thoughts
Elevation of SanRamon is ~500ft
A modest cam will have an Ica of ~58*. That's like a [email protected]
The Wallace says this should make about 164psi.
Depending on the chamber, this should go like the proverbial cat on fire.

But OP claims to have measured 180psi.
To get that, with a 58* Ica would take about a 10.4 Scr

Ima thinking there is no easy solution to this with tuning.
At least one head will need to come off, and the cam will need to be measured and degreed.
Then you can start assessing your options.

9.7 Scr is a total chamber volume of 84.74cc
10.4 is 78.43
That is a huge difference, and 78ccTOTAL, requires a very small chamber, which an OEM-360 head does not have.

The math does not add up.
