You will need a good ignition system. Something fully adjustable with today's gas.

I built basically the same engine you are building.
461 heads .040+ single relief H660CP pistons 12/18 Duntov cam because of the auto trans. I have a solid 10:1 compression. She.."talks".. to me all the time but runs like a raped ape on the big end.

Now a modern roller cam will correct the detonation problem but you need to have a cam specially ground for the 3.25 stroke 327. Most all retro-roller small block cams today are ground to fit 262-400 small blocks with a power range to about 5500-6000 rpm's. The 327 doesn't start to produce any real power until after 4000 rpm. So be very selective in this area.

You will need at least these for your 461 heads or you will pull a stud http://www.ebay.com/itm/Rocker-Arm-Studs- sb-Chevy-...

Or go with conventional screw in studs and guide plates. Good Luck.
