Yes, individual runners will help tremendously.
Running DCOES as I have can really tame the wild cams. Idles pretty good.
Bottom end torque & mid range w/DCOES are great.
The siamesed head is what lacks to make real good HP N/A I.M.O.
All I can say is try it out, 44 MM Dellortos, 13:1 compression, cam of around 246- 258 range degrees duration @ .050 should be a real torque motor.
Need to use a nice aftermarket harmonic damper/balancer.
At one time I ran 3 - 48 MM DCOEs (too big) 12:1 compression 236 in 246 ex duration @ .050 it had 220- 230 psi cranking compression.
Never raced it at a track but raced friends cars that did to compare & I would say it would have run mid 13's @ a 3000 ft altitude track, but my Camaro was about 3000 LBS
I had also Paxton supercharged my 250 blowing through the 3 DCOEs, but the best overall performance/driveability my car ever ran was w/the 3 DCOEs.
