David,
I will suggest more compression unless you are trying to run it on 87 octane regular. If so what you are doing is it.
If you have not bought heads yet what are you thinking about using.
A working running example of a daily street 383 type engine.
I have a customer in Kansas City with a 385 cu in engine with ported Canfield heads, TPIS Mini-Ram with EFI and 11.30 -1 compression in a 3,500 lb car Hyd Roller cam and .595 in lift - .576 exhuast lift 245 @ .050 in and 252 @ .050 ex 114 LSA with 3 inch exhaust that is running at 122 - 124 mph in 1/4 spraying a 150 shot.
Drives it to the track and to street races. Until this year was driving it daily and it was first fired up in Feb of 2002. Still running now with no issues and has never needed to re-adjust the rockers from my first adjustment on my engine stand. It is revved to 6,800 rpm frequently.
At 3,700 lbs he drove it as a highway car and averaged 20 mpg with it while highway cruising with a 7004R. Now it has it's second turbo 400 after busting two built Jet 7004R trannys.
You can likely get more power with a carbed engine in yours. I am trying to show you that using the HYD Roller is not that bad if it is set up right and benefits of higher compression in street cars. BUT the compression you named is better for using cheaper gas.
The engine. Note the date stamp. Car has been running that long with only the intake gasket changed.
