Welcome to the forum. The heads definitely need compensated for and you're out of injector. Are you wanting to try and tune it yourself?

It should run fine without a tune since the Maf is calibrated, obviously better with a tune but should be fine without, I ran an E cam performer headed 30lber and calibrated Maf combo for years without a tune, only tuned it since the supercharger

I was thinking about getting either a BAMA 4bank or Moates QH because i want to delete the egr and all of the smog functions.

The QH will give you more control over the ECU as it's a more powerful piece of equipment. Not sure about a price difference, but the Moates chip is $250 brand new. As for the 24s, I maxed a set with stock heads. Have you been able to run the car since you got it all put together?

The heads cam and intake add around 100 HP so there needs to be more fuel from somewhere. Throw in those injectors or even bigger ones and tune it.

Yep. The 24s may not lean out since you're using a GT40 upper and lower, but they'll be close. Regardless, it needs adjustments you're not gonna be able to compensate for with 'calibrated' parts.

something isnt right then, with the stock injectors and maf it should run just as good as a stock engine

check out the pre tune info and make sure nothing is off

Anybody have an idea roughly what kind of horse power I should expect from this engine?

So....I finally got the car running and it seems to be okay, not sure I like the cam choice because of the in town driving. Still want to get a wide band installed and do some tuning because im sure it can be better....the suspension is shot so that next on the list.
