That's the typical "bad hole" on a Chevy. Kind of like #7 on an ls motor

I would have to say as well on the SBC and BBC that if you were going to pick one commonly hot hole, it would be number two. There are a number of ways to approach fixing the issue. ICT, jetting, compression, cam, valve lash and so on.. Not sure on all the particulars in this combo, but it may be as simple as the whole combo's a little close to the edge and the #2 is just first to check out.. Please feel free to give me a call if you'd like to better discuss your deal.. Thanks, SJ
