Im running the elite engineering can.

my thought was... im running 12psi boost on a stock bottom end lt1 with expensive afr 195 comp ported heads.

why should i ‘dirty up’ those expensive heads with oil blow by

its not that my engine has a lot of blowby, the problem is when you let off the gas (and go into vacuum) the check valve opens and Any blowby gets sucked right into the intake thru the pcv system.

when i eventually have to tear this engine down, i expect to see it spotless inside (the meth/water inj helps ‘steam clean’ everything too

I believe you are right. When I was running E85 on my 87 I pulled a head after 20,000 miles or so and the chambers and piston tops were very clean. The motor had a lot of miles on it.
