Ports on a torker II are smaller as SOP than the performer RPM.

Openings are 2.03" x 1.03" for the TII vs. 2.06" x 1.10" for the RPM.

That trend goes most all the way up into the plenum as well,at least as far as I have checked in the past.

So that kinda makes up some for the single vs. plane dual plane thing.

Understand that on any kinda ported heads,if the torker II is'nt port matched to that size,the intakes openings are gonna be waaayyy smaller than the ports will probably be.

I had to do quite a bit of port matching work to get my TII to match a fel-pro #1233 intake gasket.

Heads are 250ish CFM #96's (RAIV port sizing).

TII seems to be closer to the stock port size,and the RPM seems to be closer to the RAIV/H-O port size.

With the right port work,I've seen a couple TII's surpass the RPM and rival a victor,but that amazing feat has always taken some additional heli-arc welding on/around the intake ports/openings,as they did'nt leave much extra material around the ports of that intake.

I like the TII just fine myself.
I like the tomahawk/hurricane too.
I dont necessarily buy/discriminate based on country of origin.
I leave that to others to decide for themselves.
I like the RPM too.

But the OP did'nt ask us about the RPM,so I did'nt feel it was "in the running" here,especially seeing as they have a harder time fitting under the hood of a second gen bird.

Also,if I'm using a holley,I prefer the TII across the board.

Now should Edelbrock ever "go the extra mile" and make us a dedicated square bore flanged RPM intake,then wow is all I would be able to say,and that would likely become my new "go to" intake for street performance based pontiacs.

It would also be nice to see them make both the TII and the RPM in "skeletonized" version without the exhaust crossover provisions like those "other" intakes are made.

FWIW
