OK first off I am expecting lots of kickback.

Looking at a lot of ring stuff online. Part of my old school 327 build. I have ductile iron rings. Looking at stuff on ported rings. Got me wondering about filing a small port in top of rings to give same effect to cheap=o rings. So give me shyt about why I should not give it ry. Hell 100 bucks worth of rings and never really know benefit w/o dyno is only reason I have come up with. So go for it convince me not worth or band idea.

I have a close friend who milled grooves in the top of rings years ago. You had to be super careful the way you do it so the Moly didn't get kicked off by the end mill. Filing though????

I look at it like, they are your rings so do with them what you want no matter who thinks otherwise. Why do you feel the need to get confirmation on here?

I do not need confirmation. Just figure get others ideas on doing so and maybe other way of doing. Hey if nothing else you will get reason why you should not do it here. Maybe one reason as to why not to will be a point I have note examined.

I figure moly rings will cause issue with chipping. Old cheap iron rings probably not so much. I figure filing with fine file will lesson the chipping and will be easier to keep control of depth better.

I agree with Curtis, no reason for you to NOT try something that you want to with your parts.
2 things that I would be concerned with, if they were my parts:
-Would I be introducing a potential failure point? A broken ring could cost you a bore job on 1 or more cylinders.
-What is the potential gain? (The old Risk vs. Reward question). Whether this is for street only, street-strip, or bracket racing, would I see a gain of .05 or better? If not, I would probably spend my time on other things.
And of course the other questions in my mind would be things like: How many grooves per ring? How deep do I cut? How do I make the cuts consistent / uniform? How many hours will it take?

My only real concern or reason to think what the point. No way in hell am I going to run this thing on dyno. Well not unless a bench race bs session turns into a bet. Then anything can happen. So will not really know how much its worth.

Not a race engine and not really a typical street engine. More a street toy that might hit piedmont few times. While probably never see dyno. I can see me making few runs. driving it home dropping pan, popping off heads and yanking the rack. Spend weekend filing rings. Pop back together and go make some runs. Oh I see so many sideways jokes in that last statement. LOL

Hell its a play with engine and that sounds like fun deal to experiment with. Dang should have been born rich. Then could just play with engine stuff.

No reason to do that if anything it may LOSE horsepower. The whole deal of gas ported pistons and rings is so you use lower ring tension on cylinder walls. Less friction and energy loss. If you modified those rings you would still have stiff ring tension on cylinder walls and even more so if the gas porting worked.

And I believe those rings have more space behind them to allow them to get the pressure behind them and push to cylinder walls.

With typical gas ported rings and pistons there is not much friction on cylinder walls until you are building cylinder pressure. So on downstroke and exhaust stroke it is not wasting much power. It is my opinion if you cut grooves in standard rings you would still have lots of friction and none of the benefits of gas porting.

Maybe right Curly, I do have low tension oil rings coming for engine. Along with thinnest ring package I could get w/o big cost jump.
