Cylinder Heads that have been "worked"

[383 Sleeper]

I have stumbled upon a set of old AFR 190 heads at a great price. They supposedly were upgraded the 2.06 intake valves 1.76 exhaust valves and the intake runner was supposedly opened up to about 210...

Well the intake and exhaust valves size checked out. so I don't think the guy is lying. But there's a series of stamps on the front machine of the heads that somebody put into them. Is there a set standard for what certain things mean? is there a universal guideline chart for abbreviations that heads guys use as a standard to tell what's done to them?

I've searched all over the internet and could not find anything. Hopefully someone can shed some light. Thanks in advance.

Pics of the markings? Maybe they were milled and the markings could indicate how much?

I'd rather not disclose what it says just in case. This things going in a grudge car so hopefully I haven't said too much already.

Short answer to your question: No. There is no set "shorthand" that carries from one head porter or machine shop or engine builder to the next.
Whatever the chicken scratch is on the ends of those heads, only the guy who put it there can translate.

While I can understand you not wanting to "give anything away", asking for help in translating some stamped markings without being willing to divulge what they are puts your chances of success into single digits.

Here's an abbreviation for you. AFR stands for air flow research. /thread

thank you very much for a real reply. You actually answered the question I asked and didn't come across as an a-hole off the bat. If I wanted what the other guys said in their reply I would have posted it on Xceedspeed.
