Have bluethunder heads on my 460- 400cfm heads. I just dont know the tbi's. My daily truck is a 60kmi 86gmc 4x with a fresh -3kmi-194 /72cchead/ full bolt on 5.7w rv cam. Tows my falcon around well and will burn up expensive tires. So how much @.050 for the tbi 220,230.more...roller I hope....found some iron torqrs for $500 un-assembled.
TOO MUCH DURATION, for a tbi setup. 212 is about max but the cam tech could recommend better.

On those heads, that's pretty high for unassembled. Check out Ebay stores for a set of assembled small top line for cheap. I think I seen them for 376.00 or 476.00 don't remember.
