You all have good points, well taken! Thanks for your opinions! Brad,Ronnie..I still have to purchase a carb. Do you think a 950 is still the way to go...even with increased air flow,after getting the heads CNC'd??? I'll be checking the P/V clearance shortly,and would like to increase the CR..if the clearances allow it! I'd still like to keep it pump gas friendly,and wonder if 11.5-12:1 will work? Currently,it's at 10:25. THANKS again in advance for your opinions! Randy B.
