does anyone know if there are ANY roller lifters that will slide right into a 305 v6? I think I may have a lifter going bad and wondered if this could be a possible solution. not looking for a racing engine, just a solution to an issue that I have. I will go with flat lifters but just throwing an idea out there.

If you have lifter wear, there will also be corresponding damage to the cam lobe it's riding on. I don't think there's a suitable roller lifter that will interchange, and there would have to be a fair amount of modification to the block to keep a roller lifter running in line with the cam lobe. Flat lifters are designed to spin in the block- - -rollers have to stay aligned with the lobes.

A roller tappet operating on a flat tappet lobe will have profoundly different characteristics - especially much reduced valve-open area, and large changes in tappet acceleration.
Don't.

Oh, the noise that made me start wondering is a bad exhaust gasket, guess I was jumping the gun a little bit.
