Advanced Induction 226cc CNC work
Got my hands on these, so I thought I would post some pics for those that are interested. Heads had previously had a clean-up mill of about .010 done. Heads have been cut .030 more by A.I. bringing compression on a stock short block to 11 to 1. All flanges were milled smooth also.

Flow numbers are posted on their website I believe. A CNC doesn't have a good or bad day, it produces the same results day in and day out, so those "old" flow numbers would still be valid.
226cc is their 243/799 casting program. These are 799s.

My valve guides weren't worn out but if they were then I woulda let them replace them, and yes I had them throw me a set of the Lunati's on the heads before they left.

I wonder why is it that TSP doesn't port their 799 chambers like this on their LS6 stg 1 and 2.5 heads?? Their chambers are like this:

I'm gonna stick with the LS6/stock MAF/SLP lid at this point. After I get some solid baselines I think I will do a FAST and an 85mm MAF and upsize lid and see where that takes me.

On the intake port some texture helps mix fuel and air, but most will fully polish the combustion chamber from what I've seen. One perk of doing this is very little carbon build up in the head chamber.
