Allright thanks I will go out there and see if I see any other stamps on it but thanks for any help I can get I'v had these heads for a couple years and never really thought about them till now since the do have a smaller 58.2cc thought that might help with compression
Why would there be stamped/embossed ID on the combustion side of the head?
If these are in fact A3 heads (A3 heads I'm thinking of)... I'd buy the off you
Ya I was kinda thinking the same thing ( about stamped on other side ) but I will never doubt anybody cause there is always somone out there smarter than me Im just tring to learn as I go so what other info on them is there to help me id them???????

The early 289 & 302 heads were stamped on the lifter side of the intake port (underside)

Ford stamped a bunch of heads on the combustion side. Just checking to see if there is anything there is all.
So would you replace stock 92 heads with these heads or not any help would be great Im more of the bolt on upgrade kind of guy so I need some help from guys that know more about these thing than me thank again for any help
Are the valveguides canted?
Are the valvespring seats offset from each other?
Are the heads aluminum or steel?
What heads are you talking about and where are they stamped?
This is interesting to me.

yes there is a big bump like right in front of the valve stem in each exh port ?? why whats up with that???
You'll want to knock that off with a grinder if you decide to use these heads which IMO are not as efficient as say... E7s.
