I would up the compression (as Pat D suggested) and, since you already have the 44IDF's, try them. What size venturis do they have? They'll need 38's to get the most out of the carbs. 48's will emphasize top end horsepower a little more, while leaving the lower midrange/bottom end (and throttle response) a wee bit softer (mind you, with a 2332, the size alone will make bucketfuls of bottom end, no matter how high it's made to rev!). I would expect the 2242 (248° @0.050"), being ground on 107° lobe centers, even with 1.25 rockers (which will add 4-5° to the @ 0.050" figure) to be done by 52-5500 rpm so I don't expect 48's to really add much except to extend the top end a tiny bit, but I haven't built hundreds (thousands?) of engines, so take my advice for what it is. What's the compression now? Is it running so you'll have something to compare it to?
Also, Gordon has some good points. Al
