454 Combo, Fast xfi and a set of Alu heads

Hello.
My ride is a 1969 Camaro.
Tremec TKO-600 transmission. Rear 9" Strange 3.50 Gear.

I have bought a used Gm Crate engine.Gen VI 454.( in good shape)
Partnr :12568774. 425hk/500TQ. Compression: 8.75:1 (iron heads) Camshaft :Hydraulic roller. Lift:510" intake, .540" exhaust. Duration:211-intake, 230-exhaust @ .050

Planning to buy : FAST XFI injection: 3011454-05 or 3011454-10

And change the Camshaft for some more duration: (230-240) !! ?
And change to Alu Heads: 110. Combustion Chamber Volume.
Instead of the original 118cc iron heads..

For example : GM 12363390. Completely assembled with 2.25"/1.88". 290cc oval intake ports. 110cc combustion chambers.
Most Street engine, but some strip. HK ? 500++

someone who will help me find a good combo
Head type?

Think I'd talk with the techs at Comp on this one! They've worked with FAST on cam profiles that work exceptionally well with the EFI!!!! No reason to guess when the research has already been done for you! Same with the heads, ask the guys at Comp and FAST what heads they've used in their dyno testing.

Like Dave said, you'll have a much better chance of getting an answer if you pick up the phone and talk to the guys in person, real time. Everyone gets hammered by digital communications these days, and companies who care have qualified techs ready to talk. Suggest you pick up the phone on this one.
