Default Engine Rebuild/Install (PICS)

Hello All,
Last year about this time I made a few posts for info/help, and you folks always came through (Thanks).
I am putting the engine in the weekend of 3 June, so here is a pic, I will post one of the heads I ported later.
http://i58.photobucket.com/albums/g2...s/DSCN2025.jpg

This is my 94 auto, daily driver.
Here are the mods:
GM Hotcam
Cloyes double roller timing gear set
1.6 Crane Gold Race roller rockers
EM long tube headers (ceramic coated inside and out)
CSR electric water pump
stock LT1 aluminum heads ported & polished (I did the P/P)
Comp Cams (26915) Beehive valve springs/retainers
Cut-back valves and 3 angle valve job (stock valves)
ATI SFI rated balancer
MSD Superconductor plug wires (red)
Upgraded to 95 timinig cover and vented optispark
EGR deleted
Air Injection deleted
NGK Iridium Sprk Plugs
Cats Eliminated (sorry Bogus)
LT4 Knock Module
pcmforless tune

I will stay with the stock exhaust at least for now.
I painted the block red with ceramic high temp paint,
powder coated the PCM case (red), throttle body (red),
intake manifold (blck), thermostat
housing (red), water pump housing (black),
alternator/ac compressor
bracket (red) etc.

Heads:

Thanks for the compliments, I don't have access to a 1/4 mile track locally, we have an 1/8 mile.
A younger fellow I work with and I are going to line them up on the strip after I get it broke in. He has a 02 Trans Am WS6 with the LS1.
I think he dynoed at 318rhp.
I will let you all know what kind of time I run, I hope to get on a dyno also, will post the results.

Update:

It is ALIVE.
We got the old engine out in 3 hours. Took awhile longer getting the new one in due to several things including changing out the valve retainers/locks that were for a LS1. I also had trouble with the engine rotating very hard by hand.
We pulled the pan and a friend of mine found the problem, I nicked one of the connecting rod journals on the crank and it was digging into the bearing.
We corrected the problem, finished the install and she is runnng great.
I will go the the exhaust shop this morning and get it hooked up properly, and flash the tune to the PCM this afternoon.
Many thanks to all that have provided advice and help.
