cylinder head question?/AGAIN

Trans is a 4spd
Gears I was thinkin 3:55 or 3:73 sure grip its a one legger now with 2:76 or 2:93??? A highway gear is in it right now
Tires are 28 inches?? 275 60 15
Air gap intake
Want it to be a street car but want to hit the track everyonce in a while
I want a "lopey" idle
And a hyd. Cam

Sorry Dustya but Air Gap is an intake name for Small blocks, if it's an Edelbrock it should be cast in like Performer RPM or Torker.
