is it worth it to replace lifters on cam swap? i'm installing an ms3 cam in my car. it will be a cam only build with pushrods, springs, oil pump, headers. i ordered ls7 lifters, but didn't realize you had to remove the heads. now i'm looking at head gaskets, bolts tons of extra work and probably several other parts i'm missing.
so my question is with an ms3 cam install is it even worth it at this point? if it isn't i may just hold on to them because i do plan on getting new heads someday (no time soon).

How many miles on stock lifters? It's all about how comfortable you are not changing them out. Plenty have just left stockers in with cam only setups. I left min stock. I have been cammed for 15k miles. I do plan on a head upgrade and will prolly change them out next year but so far so good. Others have not been so lucky but I think that number is slot smaller then the number of people who have been just fine. If you do end up pulling the heads have a good vale job done on them.
I wouldn't mind keeping stockers in if they were low miles and the cam was mild, but with a big cam like an ms3 I would def spend the extra 2-300 bucks on some morel/Johnson lifters and new head gaskets and bolts....but unless you plan on drag racing every weekend and beating its *** you should be fine, but remember its a roll of the dice...

the car has 22,000 miles. it will never see a drag strip. it's my cruise around and blow off some steam car. i'll go ahead and change the lifters to be safe. i had planned on doing heads too until my wife chimed in 
after that i decided to go cam only. that's what messed me up. i dont have any experience with cam swaps and i guess i didn't read as much as i thought i had.

Why install a probably dated cam design? Have Martin @ TICK performance or Patrick G. spec you one. I doubt you could find one negative post about either guy. Martin has quite a few new series of cam threads going here @ LS1tech. with STELLAR results/happy customers. Just a thought.
With that low of miles I would pass on the lifters. You have to get gaskets and new head bolts and its a good amount of extra time. However it is peace of mind to do them....me personally I would and did pass on them lol

The MS3 is a proven performer and there is nothing wrong with it and its "dated" design.
