I just bought a tr 224/224 .563/.563 112 lsa cam, and I'm probably going to be getting a pair of tr gtp stage 2 ported heads. I know the heads have new valves, springs, and retainers, but I need to know what else to get. I already know to get pushrods, but do I need lifters and rocker arms, too? Also, should I look at a new timing set, or can that wait till later? Lastly, I'm planning on running nitrous (125 dry shot) in the future, and was wondering if I should go ahead and upgrade my injectors while I'm in there. BTW, if it means anything, I'm also lined up for a spot on LS1 Edit.

 

a h/c gasket and bolt kit. what year and how many miles do you have on your car. if its a 98-00 get a new oil pump and chain and if you have high miles consider some comp 850 lifters since you'll be pulling the heads anway. new rockers are optional, the stockers work just fine.

 

The car is a 2000 WS.6 w/about 65000 miles on it.

 

then i'd do at least the pump and chain. lifters are up to you. im running a ported ls6 pump, rollmaster double, and comp 850 lifters myself.

 

I'll probably go ahead and get some lifters, b/c when I put this thing together, I want it to stay together for a while.
