Ok need some input going todo a cam swap on my z28 just wondering wich lifters to go with or will my stock lifters be ok have 150000 mi on motor thanks guys

 

you should inspect carefully the rollers on your lifters. if good you can re-use......but cam companies recommend replacing lifters when installing a new cam

 

You can reuse them if you like but 150K is a lot of miles. You can use lifters for a
LS engines or even Caddy racing lifters. The GM sourced parts are reasonably priced. Three used to be issues with aftermarket lifters from Comp but I believe that's well behind us now.

 

I looked up these part #12499225 will these work for my 96 lt1 will stock retainers nd spyder work with these if they do fit my car

 

Yes, those will work...
