Im doing the water pump on my lt1. Should i use RTV or should i use the gaskets i made from FELPRO?

I always use the proper gaskets with just a little RTV to hold the gasket in place during the install. I try to never use 100% RTV on anything that actually requires a gasket, thats just my opionion thought. If you do use RTV on the waterpump make sure it is the right kind, they actually make RTV for waterpumps that is resistant to Glycol
