What heads do you have? LS7 intake valves are 2.20 inches. They probably won't fit in the heads you have unless you have the valve seats machined. If you do rockers, keep your old ones and do the trunnion upgrade. That will extend the life of them considerably. The LS7 lifters are decent. I'd look into a set of slow leakdown lifters as they are less noisy as far as I've read and been told when emailing Brian tooley racing. If you have cathedral port heads on the car right now, you might want to look into trick flow 220 as cast heads with ferrea valves. That setup is highly recommended from many experts I've talked to about my builds. You may want to consider sending the heads to west coast cylinder heads. They do pretty good work.
