Default Update on my */C S1 rebuild

I've got so many old posts on this (depending on what issue I had) it aint even funny, but it looks like the time is growing closer to wake it back up from a commatose state

Here is what I have done since I started tearing it down:

HEADS
De-carbonized the heads, just a general clean-up...nothing special there.
Polished all the valves, then lapped in head...again, nothing special.
Updated valvetrain to 93+ roller pedestals.
New stem seals.
Aluminum V/C'* from an S2 F-Body. Yes, they fit.

BOTTOM END
New crankshaft, oil pump, lifters, knock sensor, all new gaskets everywhere. Rods spec'd out fine, so I left those alone.

MANIFOLDS
Intake got bead blasted then painted black, exhaust got soaked in full-strength Castrol SuperClean for a few days. Found MAJOR cracks on front manifold, so I trashed it and found a crack-free one in the boneyard, rear mani was fine. Painted the front high-temp black and will header-wrap everything when the Turkey Run comes to Daytona (can get it dirt cheap then). Oh yeah, took off the front heat shield too.

SUPERCHARGER
Was already rebuilt. Currently working on a custom intake system...I really don't want to go ricepipe because, well, that'* the EASY way. I've done away with the purge caninster, and if I go with a smaller washer bottle I should be able to come up with a really nice CAI system. But since this system is NOT required to get this thing running, it is not priority.

I've also done alot of little stuff, like soaking the injectors, replacing all those seals, painting this n'that. I'll have a few pics up later. [/b]

How so? I am seeing it this way: Wrapped manis *should* drop underhood temps substantially, thereby dropping ambient air temps. Besides, I am not looking to make all-out power with this motor...I'll reserve that for the next motor I build up. Instead, I am looking for longevity. I'm not planning on taking this car to the track, and here in Florida heat is already an issue, so the more I can control the heat, the longer my rebuild should last. Theoretically.

EDIT: Here are the new pics. Stuff is still missing because the engine is going to the shop tonight for some crank yankin'

Looking good. I like the way the Lower intake manifold looks. what type of paint did you use.

Dupli-color high heat flat black then cleared with same type. I think it will all look pretty mean once it'* all together. Besides, I had to make my Floz look good on there, and I think black does the trick.

I've been repainting the strut towers and almost every engine part that has come off the car. I didn't want to be too embarrased whenever I open the hood to show off my new build

header wrap keeps the heat in, yes. but it also transfers some of that heat back to the combustion chamber, raising temps and KR. i asked this same question because my pems were wrapped. i cut it off.
