340 T/A (U code) head value? (Pics)

I have a set of the ones that were produced in the 90's for stock and super stock class racers. The ports are large enough to push a coke can into and were obviously done by a head shop. W2 rockers will not work unless alignment is not important to you. Mine use a .500 offset on the intake and standard offset on the exhaust. I am using a MP pieces that is actually .450 offset but I can shim the rocker enough to get decent alignment. I will be flowing these soon to check how good they are.
Thanks for that post.
Correct me if I'm wrong, but don't they accept standard intake rockers but W2 exhaust rockers?
I found what I was looking for but not what I thought it said. I have heard various people trying the OE 6 pack rockers on a W2 head with various results. Having not been there myself, I could only answer in the way I did. The manual page pictured below.
