1206 gaskets! Wow!!! What head are you using?
as far as a cleanup goes, im not into porting but I have heard of people cutting the miniram open and doing some heavy duty port work and then resealing it up.
You can chat with AKS Racing found on that othe forum. He has flow number for all the miniram models.
The bigger gasket size the more they flow from TPIS.
I run a 1205 gasket. From looking on the inside of mine there are some rough spots that can be smoothed with a grinder and if you do not want to cut it open you may want to hand port first and then have it extrune honed (sp?)
Good luck!

Heads will be AFR 210 or Canfield 215 CC.
Your right tntcorvette, I have not heard of many people porting them much, but the MRII is a 1206 Gasket and this will be for a 406 motor. Dont want to port the \m much really just clean it up.

well a hand job with a grinder and air tools will be fine.

I've got one in my garage right now that had the full cut open, port, re-weld job done.
Man what a time consuming job it was too.
Had it done in CA by a guy who use to port for Extrude Hone,l Bob Jones. Bob took lots of photos and is trying to get one of the mags to run an article on his work. I think Super Chevy, Corvette Fever or Vette; forgot which.
On the flow bench, the MiniRam created turbulance right at the 310 cfm range and this was after considerable port work but BEFORE it was cut open and re-welded. In order to hit the 700 HP level we want we figured to need at least 340 at the VALVE.
In order to hit that (at the valve) flow number, the intake has to flow CONSIDERABLY more than the head in order not to present a flow restriction to the head.
So, if you have a set of heads that flow, say 290, but your intake only flows a like amount - 290 - then the heads WILL NOT FLOW 290 AT THE VALVE. The intake must flow more.
So it depends on what power levels you're shooting for.
This is serious stuff (way over my head) and best left to someone who really knows what he's doing. You'd be surprised at just how little metal, removed from the wrong spot can absolutely KILL flow.
BTW, three different flow benches confirm we got the flow we needed.
Hope this helps, Jake
