increasing compression ratio
I was wondering how much power i could get from my 302 by increasing the compression ratio of my GT40 heads from 9:1 up to 10:1 or even 10.5:1?
How about a 200 straight six with 8:1 compression going up to 10:1  Thanks, note: i haven't installed my GT40 heads yet so any suggestions as to anything else i may want to do is greatly appreciated (i'm going to gasket match, don't think i want to port/or have them ported unless it makes a huge difference) Is increasing the compression ratio worthwhile since i'm going to be using nitrous oxide - i don't want to blow holes in stuff.
