For Pump gas 93 octane we suggest a compression ratio of 8.75-9.5:1 on aluminum heads depending on pulley size and boost level. If you currently have a pump gas compression of 10:1, you may be able to achieve this compression ratio simply by changing to a thicker Cometic head gasket that we offer.

Easy install - take your time .
Hood clearance is a issue its so close you might need to turn hat around to the side. My install was on a 68 GTO it can be done with some slight mods to spacers and Alt pulley . I ran a cold air pipe to the unit from the front to get the most out of the unit 6-8 PSI . Then i added a intercooler that woke her up even more.
Fitech 600pa for timing and fuel control
