While understanding there are other variables involved, what would be a good estimate in power these make over a well CNC ported 243 (AI, etc)?
I'm looking at the AI 226 CNC program and if these are really only say 10-15whp more, I need to decide if they're worth the almost $1k extra in cost..
How much do the lighter valves run?

The engine will be alot more responsive as well due to all the airspeed these heads produce....and they still flow enough to generate 550+ HP at the crank
I shipped a few of the new 205's already......I think when the results and feedback start rolling in you guy are going to be impressed!

Jumping/bumping in for my internet glory! j/k
Pretty sure I was an early adopter as I jumped in late March but just got these installed last Friday.
I don't have numbers to offer yet,(I could get a sound clip, but that's not really the point) but I'm working on a full tune and dyno within the next year (long story).
Just some feedback, Tony was great to work with on this project and helped every step of the way, from design to install. Really appreciate his expertise and guidance. Above and beyond for sure.
Good luck with the product line Tony, and I'll get some rwhp/rwtq digits ASAP.

Unfortunately I don't have a proper dyno on it....yet.
I did get it tuned and it's READY to dyno, but it is now in storage for probably over a year. It's a long story, but the word I got from the (very reputable) tuner is over 4 bills butt dyno, if that helps.
I don't expect over 430 if I even hit that, but I think it's solid over 400.
Pre heads it was pushing 385 on 93 and pulled 398 on E85 so it should be close.
Sorry I can't give you better info.
Even worse, I've not even driven it since the tune.
I'm so ashamed.

I was about to pull the trigger on a set of ported 243s from AI but with new vales and springs I am knocking on $2k door. That is really close to a brand new set of sportsman heads. As others have asked already I wonder how the MMS 223 stack up to AI's 226cc program.
