I have a 350tpi from a 92 z28. Im replacing the stock heads with corvette heads. I put in an lt1 cam and going to top it off with a stealth ram. I picked up ls6 springs and the retainers. Can i use the stock roller lifters and pushrods or is there a recommendation?

 

You prob can use both n be fine. But LS7 lifters are better from what most say and many use them(internals are slightly diff), got a few sets myself for future SBC projects. It's always best to check pushrod length when you change stuff up, stock ones are weak anyway. They were designed to flex a bit for noise reduction, so I always change to better pushrods.
