I don't have any issues with ignition cross fire via the wires since routing them safely away from each other is easy. The cap is more of an issue than wires ever will be.
Well your heads can use a cam as big as 278/280 and .700/.700 which I have personally run on 91 octane and 11.5:1. Can't say how long the lifters will last with those spring pressures but it will need the $800-$1000 ones.
If you want to stay around 400-440# over the nose you can run a lesser expensive lifter ($450-600) for a long time and a roller cam 250/250, .600/.600.......but your heads are better than that.
Compromise, compromise, compromise.
I have this cam and will be using the 440EZ heads, what is the limiting factor for lift? I am slightly above what you say the max lift is for this head.

Man some big claim numbers for EZ heads.
Sorry I misunderstood, what horsepower numbers were those?I was referring to HP numbers not flow numbers. My MW CNC EZs were done by Modern Cylinder Head
Did you girdle the block?graph and pics:
Girdles don't do anything!Did you girdle the block?
Why do you say that? What have you found? I ask with all respect since I know you are well established and experienced, so Id like to hear more on it since we all fear the cap walking issues and block failures.Girdles don't do anything!

Cap walk is usually brought on from detonation or too much load on the engine. All girdles do is sit on top of the caps...they only locate the stud or bolt, absolutely they do nothing for the cap! Ask anyone who sells them to PROVE they work...can't be done. The registers in the block are what hold the cap still, so the tighter they are the better, but they can't be too tight or you'll tweak the cap. Cap walk is the caps vibrating under harmonics...how can a girdle that's not actually part of the main cap stop that? Even if the caps were cast together it won't stop vibrations the cap sees when under detonation. If the block flexes too much, this can also cause cap walk because if will loosen the grip it has on the registers that hold the cap in place....still not a damn thing a girdle can help with....;-)
