I scored me a 1998 vortec 350 engine. I am going to build a 383 for my monte for some strip action. The buildup that I am going to do is the one that Tech inspector layed out on page 5 of this forum. I am going to use a comp cam 230/230 286 XE. Can i use the OE lifters? They look to be in good shape. The heads are casting 062. Are the 906's better? Thanks for any help.
