Looks like a good combo you got there.
It's also nice to see some people take advise of what I always suggest(zero deck).
Also w/the 1.84 intake,,,,,why loose some bottom end & mileage w/the 1.94 especially w/the combo you have there.
Your cam only has 206 duration @ .050,so pushing it to 5000 RPM will be out of the cams power range,it could go to 5K,but probably not make peak power there.
Comp says 1000 - 4200 max RPM.
The main thing that holds back the 250 from reving freely & smoother is the stock damper,,,,by installing a good aftermarket damper,or a stock SBC 300 Horse 350 CI 8" damper will be much better.
What kind of compression are you running?
It's been so long since I had a stock 250 running,but IIRC,they would rev to 4800 RPM,would not make much power there,but that's what I remember shifting to 4800 in my Moms 73 4 dr Nova 250 w/a PG.
If you want to turn to 5000 RPM,the next size cam would be better ,the 260H cam has 6 more degrees duration than your current cam.
