Can somebody give me or point me to the following info on a 1961 283?

a) what newer heads, if any, can I use? I have domed pistons .60 over and would prefer to run pump gas 93 octane max...

b) what is the normal range / max rpm I can expect?

c) I have a Holley 7448 2b sitting around gathering dust - could I expect to get fair to good performance with that carb? I was thinking a Performer RPM manifold - good choice or not? BTW - I have a Speed Pro CS112R Cam, 2800-6000 RPM Range, 300/300 Adv Dur, @.050 224/224, Lobe Sep 108, Lift .436/.436 to go with it.

I'll probably have quite a few more questions as I go - this is my first engine build!

Thanks
Dale
