LOL, you listed a LS1 MAF & SLP MAF. Just keep the stock one.
I'm not sure if those heads would be best for an NA application. I'd prefer using LS6 heads or 5.3 liter heads. You didn't mention what cam you are using...I hope you aren't keeping the stock one in there. I'd get a custom grind cam if I were you. If you open up the block, get a ported LS6 oil pump and a LS2 timing chain.
EDIT: I see the cam listed now, my bad.

What are your power goals? How is the car to be used?

loli already have a few things i have a brand new timing chain and gear set, and a new ls1 oil pump im porting. i have a buddie that has over 20 years gm experience thats helping me along the way. he swore those heads will give me the best power. they're already decked and ready for bolt on. i was worried they'd lower my compression but he says otherwise.
my power goals are between 450-500 on 93 pump gas. i know its a bit of a reach but i can have the motor out of the car as long as i want. he says the stock maf wont handle much over stock but i've seen that hey can handle up to 500 on the forums. ive just got so many different answers from everyone i'd like something in stone.

i was hoping for 450-500 rwhp or is that unreasonable?
and what are your experiences with the ls7 clutch. will it hold up to my motor? the car will be a daily driver and a occasional strip car. im not gonna put alot into making it hook up because my drivetrain will not like it

You'd have to step up to a FAST 90/90 or better and a BIG cam.

i heard with stock pistons i couldn't run a big cam with those heads because the valves would hit the piston. or is this false too?
and i was considering the fast intake and throttle body down the road its just the 1k i'd throw into the intake would keep me from getting the motor in even longer.

You can run fairly large cams with stock heads & bottom end w/o having to flycut the pistons (Torquer 2, MS3, Typhoon, etc) but with those heads I don't know how it changes the equation. If you run a cam like an MS4 with stock block and heads than flycutting may be needed. My buddy fly cut his pistons and it wasn't a big deal.

im coming from the tuner world and flycutting a piston is a scary thought but i may end up doing that.
thanks for the info and im not looking for a pissing match say what ya want if im being a dumbass i need to hear it haha
the ms4 cam is a badass cam ive seen videos of it and i was considering picking one up but i can get deals on gm parts so it would be cheaper to go with the gm custom cam. i could always have them make a ms4 cam by sending them the durations and lsa

The only way that you'll know for sure whether or not flycutting is required is to check and double check your piston to valve clearance. My buddy has a MS3 in his car and another had a MS4 in his, they are badass cams. They are large cams though.

ok thanks man. i gotta talk to my friend about it and see where i stand. once i get my cam i can get my heads on.
do you think i can atleast get 400hp and 400 tq on pump gas? rwhp that is
my old 4 banger had 340rwhp and 302tq but that was from a 2.0 turbo.
