302 heads with 69 318 A-body manifolds

Hmmmmm........thanks guys. I've plugged them the little holes......on run stand with headers and no leaks.

As soon as I seen it. I seem to remember something about this issue and when I googled it shows a thread on this site talking about and grinding the head.

I'm running the stock A-body 318 manifolds. I just noticed that the manifold on the driverside is against heads. I'll post pictures.
