Gaskets

Hi guys,
I will hopefully be new to this section soon. I am doing the l32 topswap on my 05 and I was wondering what gaskets (head, intake, ect.) you guys use for your s/c engines. TIA

Head gaskets can be bought fairly cheap at an auto parts store. If you go to the dealers for the gaskets, I'll give you the numbers that you will need. Make sure to get the metal LIM gaskets...yes they're expensive, but you do NOT want the plastic ones.
GM Head set (this includes the top end gasket set if you decide to go that route) 89017824
LIM gaskets 89017825
GenV gasket (assuming you're doing this since you said L32) 12574474
The 2 little yellow o-rings on the LIM 24501563 (each)
Valve Cover Gaskets 24503937 (each)
Coolant elbows! these are crummy and they always break. 24503423 & 12565082
Throttle body seal (GenV) 12576730
You might want to get you an o-ring kit for the injectors, just for peace of mind. I'm talking about the ones that actually go onto the injectors. The kit from GM is ridiculously high, so you can be safe with getting them from an auto parts store.
You're also going to need all new head bolts as well along with new rocker bolts.

Rocker bolts (12) 24503515
Long head bolts (8) 25527831
Short head bolts (8) 88891770
