cylinder heads 66 Vs. 67
I have a stock '67 289. I recently got a set of stock '66 cylinder heads. Would the '66 set have the same CFM rating as the 67's? I would like to clean up the 66's (minor porting, new valves, mill the deck) and bolt them on this summer when I add new carb,intake, and cam and I am wondering if this will work out. Thank you for the Help!
