I would say, with a big plenum like a sheet metal tunnelram, but I have been wrong before 
great place to get them

I use them on a tall spacer. Not sure they actually help in this application but it doesn't seem to hurt.

Do you make the big spacer?

A racer friend said I was choppy at 2000 to 3000 rpm.I never noticed it till he pointed it out and said itd from reversion in the intake.

Yes, I had to make these spacers since nobody sells anything like this. I tapered the spacer to work with the shear plate and I put a profile on the bottom of the spacer to match the Super Victor plenum shape.

In most cases a shear plate is a plus but the manifold has to be configured so the reversion energy will help accelerate the incoming charge,best results gained with a trip to the dyno.Bill C.

I doubt that a trip to the dyno would reveal much. I spent 4 days on the dyno trying several different spacers and didn't prove anything.

I am thinking of running wilson shear plates on the hemi with a stageV intake, I dont know what it takes to install them but I am hoping they help. Tim

It takes a lot of grinding to use shear plates on a cast intake. That was why I had the custom spacers built.
A set of shear plates might work okay on a Stage V intake but it will cost you a fair amount of time and money to make it all fit. I spent a couple of grand testing spacers and shear plates earlier this year and didn't find any power on my 514. But I guess I did help stimulate the economy a little bit!
