I have close to what Drifter has,with alum. heads
I'm running 11:5to1 on compression on 93 pump gas.
Try using Marval Mystery Oil in your gas. You can safely run 1 point higher compression with alum. heads and be safe and no ping . Use flat top or even better yet dish pistons for better flame travel. :)
I just put on a cross ram intake and WOW. :D
