I building a 340 stroker with 5cc icon pistons and lunati 60403 cam. I have attached 2 compression calculations: 1 with factory X head and another for the 340 RPM edelbrock head.

Is it worth the money to purchase the eddy heads? The static compression with those heads will be 11.2:1 and dynamic compression is 9.5. Would I be able to run the engine without damaging it on 93 octane gas?

thanks in advance for any help,
Ray
