11.2-1 OK with 93 pump gas? P/V Clear? Dart 205's on the way 
. I am looking to mill them .020, use GM MLS gaskets and install the F14. I have been told that the compression ratio will be close to 11.2-1. Will 93 octane pump gas be OK with this set-up?
One more question, will piston to valve clearence be an issue? Thanks

With proper tune, 11.2 is fine.
Instead of milling them use a thinner gasket like .040 to increase SCR (but you better your quench, which is a + for knock control)
PTV will have to be measured

Yes you can easily run that compression on 93 I believe alot has to do with the tune on how high you can go with the SCR on pump gas. Plus our motors are aluminum so they dissapate heat faster allowing you to run more compression. As far as the PtoV clearance I'm not positive on that but I'm sure someone will post up.
