Custom EPS Cam already have it
Stock rockers with trunion upgrade

LS3 hollow int valves
PSI Xceldyne Springs
Lashway Pushrods

Thinner MLS head gaskets
Springs, undecided. I want lightweight but I'm kind of gun shy on beehives... Maybe PSI Beehives.. or I may stick with trusty PRC Dual Gold Xtremes...
LS6 Intake already have
LS6 Valley Cover
LS2 Lifter Trays
??? throttle body
SLP 85mm MAF already have
FTP 95mm? airlid
Chrs1313 Ram Air, A/C version

Also with 108K on the car would you guys throw new lifters in it?

It's got a little tick sometimes but I'm almost sure its an exhaust leak.

get a new set of ls7 lifters

Should always replace your lifters when swaping a cam

Might need bigger injectors and fuel pump to go with that 150shot

I have a walbro 340 and hotwire harness ready to drop in as well. Stock injectors should be fine..... You dont need to increase injector size with a wet shot. I'm sure at my altitude the stockers can fuel the engine with the baby cam and stock 243s...

These are often over looked when doing heads and cam sometimes cause a small leak if not replaced

12551933 this is a small gasket used on the coolant cross over or block off
12602541 cross over o-ring used in conjunction with gasket above

Ive pulled some off with both being used and some with just one or the other....GM must be very inconsistent or someone else was there before me. You need 4 of each part number, they're cheap anyways.
