Appears to be cam only, not ported heads. That would limit flywheel HP a bit.
Rather than guess at the injector size, try this. Multiply the expected flywheel HP by 0.07 to get the minimum recommended injector size. That factor assumes a moderately efficient tune (0.476 #/HR/HP BSFC) and a maximum duty cycle of 85%.
Example....
500 flywheel HP x 0.07 = 35 #/HR
