A few Trans am LS6 swap questions.

A few Trans am LS6 swap questions.
I currently have a 99 Trans am with a 6 speed. I have a Fast intake and Fast Throttle body, Mac long tubes, straight pipes to borla exhaust.
I bought an Ls6 and Ecm out of an 02 Corvette. I'm swapping it out with the old Ls1.
Are there any things that need to be changed out? Will the Ls1 harness work with the Ls6 ecm?
I'm sure the oil pan must be changed.
My headers and intake should work fine over the ls6 intake and exhaust manifold, right?
I shouldn't have to get the Ls6 ecm flashed for these mods will I?
Any help is appreciated.

Couple things, how do you know this is an ls6? Corvettes all came with ls1 motors unless it was a z06. 1168 is an ls6 block casting number but it wont tell you the year, also LS1 motors commonly came with ls6 blocks so just having an ls6 block doesnt mean its actually an ls6.
You need to look at the heads, ls6 heads are casting 243. 241 heads are ls1. If that all checks out the only way to tell what year it is would be to take the cam timing gear off and look at the numbers stamped into the cam. or pull the heads and weigh the valves

I might be wrong on this, but I think the valley cover change happened in 02. If your PCV port is off the valley cover just under the intake to the passenger side pointing diagonally forward, I would think it's an 02. If your valley cover doesn't have that port, it's likely an 01.
Of course if I'm wrong someone will correct me.

I thought it was an 02. I re-read the message and it did not specify the year, nor did he specify it being a zo6. I've been looking at so many, I got it confused. I'm going to message him today and ask specifically what year it is.
Has anyone ever heard of somebody putting 243 heads on an ls6 block, that has the ls1 cam, and calling it an Ls6 just to sell it? Or am I being paranoid? I just don't want to get ripped off again.
I read that some ls1's have the ls6 block and after 01, they used ls6 intake. I Just want to be positive it's got an ls6 cam.

Ok, so it would be wise to put a new high pressure oil pump, and new timing chain set on.
I've looked at a few, but does anyone have recommendations on brand, or best place to buy them?
Will I need new gaskets where the header connects to manifold?
Would it be worth the extra cash to add an underdrive pulley as well?

Cloyes 3220 timing set. Has the LS2 thicker chain, no clearance issues, and $35 at oreillys when I got it 5 months ago.
Yes, get new header gaskets. Exhaust leaks will really screw with your tune.
Don't worry about the UD pulley unless you're going all out. It's easy enough to go back in later and put one on.
Do get a ARP pulley bolt and don't reuse the stock bolt not even to get the pulley back on.

I agree with a new oil pump and timing chain,Im thinking I would pull off the heads and do head and intake gaskets while its on the floor. You will also get a good look at the lifters and cam then also. Just some quick things for piece of mind before all that work.

A few Trans am LS6 swap questions.
And also, do not use the new bolt to pull the pulley on, either.
If it has the original lifters you may want to replace them anyway (with stock new ones).
And do the rocket trunnion/bearing upgrade.
