valve question?

Hey guy, does anyone know what the lash on the rockers should be. I have a ls1 with a 224/224-581/581 on 112 and I dont know what the clearnce should be. I have been haveing what I think is a exhuast leak but I think its the valve train makeing the noise.

That would be a Gen III question (LS1).

There is no valve lash on the LS1. These engines were designed for a hydraulic cam unlike the SBC which debuted with a solid flat camshaft.
