Head Identification

[Pete1p]

Hi guys trying to figure out what heads these are. It appears the cylinders are numbered just above the exhaust flange and there is a sn number centered above the flange pictured below.

I think they are old trick flow heads.
The SN is serial number, not part number.
I had to call trick flow with the numbers and they told me what they were (I knew what they were, but I was selling them and wanted them verified for buyer)

Thanks man that's what I thought I'll give them a call in the morning.
