Yeah, a heavier oil would slow down consumption, but wouldn't cause the drastic change for the better like I have achieved. I would have to say that the intake gasket was definately the issue. 600 miles now and oil is still above the full line. No smoke can be seen by anyone following behind me while driving, especially when I quickly let off the throttle after jumping hard into it. Thicker oil wouldn't have made these differences, especially when I was already running 10w40 oil with either Comp lube, or Hughes lube previously.

The leak was not so obvious on mine; just a small crack near on of the port holes on the passenger side. No abundance of oil, just some slight discoloration in the corresponding intake port.

I also just put the Holley 650 dual feed carb back on and jetted it up a bit to 72 primaries and still 73s in the secondaries. Runs great, but I think I will bump up to 75 or 76s in the secondaries.

So far, so good.
