Convert to replaceable idle air bleeds?

I can tell you from my experience that some cams won't like a low IFR. Mine hates it. I know that flies in the face of everything the smart people say (and they are infinitely smarter than I am) so if you move them down and it ain't happy, don't be surprised.

Sometimes it is what it is.

Also, to try and remedy this issue, I've purchased an antireversion plate. The problem with that is it's worthless if you don't modify the top of the intake manifold. And I'm not motivated to pull the intake, weld it up, grind it to size, surface it and then put it back on.

I suspect that plate may make it so I can use the lower IFR. I do believe that is the optimal position.
