Excellent info in this thread ^.^d  I'll add: Anything that creates a higher pressure differential across the turbine will improve performance. A less restrictive conduit after the turbine should improve performance since the pressure differential "seen" by the turbine will be greater; less work put into scavenging = more work available to spin the turbine. Improved power (within thermal/mechanical limitations), and BSF. This same principle can be applied anywhere from the point of air intake to exhaust exit. Hope I never have to do a valve job on our ISM but if I ever do, it's going on my flow bench for some tweaks. ;D

I hope you have sturdy bench if that ever comes to pass.

Like the ideas stated.  I lessened intake restriction via a blue tech air filter, , adjusted valves, upgraded air pressure, reolaced bad cam postion replaced fuel lines, replaced Winn fuel filter, replaced alternator, added solar to kick off alternator loads, , changed cooling systems fan controller,  added low friction tires, replaced suspension grease seals, synthetic oil in hubs. Aero 5050xl  resonator beautifully installed with welded connections. 

Now the increased upstream air flow can help the lesser back pressure spin up the turbine wheels.

Remove loads, increase air in. Let the air out better.

Nice ride now.  Now finish electric issues, now finish steering box.  Fixing that proactively.  Leaks.  Fix before failure

I ordered the Jones JT5050XL.... Now to decide If I want to try the install or find someone to do it...  Thanks for all the input...

Great!  Do not forget to update us on your thoughts of how it performs once you get it installed!

LOL... would have to build a big bore adapter and outrigger support to do it. Nothing fancy like the Lucite commercial jobs; no reason to see inside for dry flow. Particle board with foam seals gets the job done well. The bench itself, a home-brew copy of a Superflow 300, will handle the weight, I think ::)

+1 on the let us know how it performs. I may be doing this too. ...though I hate to pull the original muff...looks like it could easily go another 20 years.

Keith, I found the SS elbows on Ebay and bought the flex at a local autocrats store .  Flex isn't stainless but I figured the original lasted 20 years the new piece would outlast me!

Boosted engines respond poorly to the time of porting .  If you have any sharp  edges, clean them up, but the pressure gets the air inside well and the injection makes sure that all are fed the same .
 If you want to go crazy,  we have a flow bench , that I rent per hr.

Hey, Mike, assuming your response was directed at me, (flow bench) I agree that port improvements on a forced induction engine have lesser results, vs a naturally aspirated mill, and has to be done conservatively. My main goal would be to improve efficiency. ...smallish, quiet ports. No matter, it's unlikely I'll ever have a big six head on my bench, unless it was off the block for some other reason.
