Small block engine mount question

And thanks for the heads up about the manifold. I’m not at home, but in pics on my phone it doesn’t appear the heads have air injection ports, so I should be good. I’ll test fit the manifolds before I drop the engine in, just to be sure

I have a 79 318 and it has the ports. But I got lucky that the 67 up 273 manifolds fit proper.

In the post it mentions that you can not grind the riser on the head as the water jackets are too close
