Help me identify these heads

So I purchased a set of 862 heads they need to be milled to clean up a cylinder. Was told there is a chance they were ported and polished along with larger valves installed by MTI. I have done some looking and seems they very well could be they do have 2.05 and 1.6 valves. I have attached some pics. Does MTI stamp any specific numbers to identify there work. Thanks in advance

Ported, yes, polished...... don't think so. Too rough a finish.

I agree should be better than my stock 706 heads.

862 truck heads better than 706 because they don't crack. I put 2.00 inch intake and 1.56 exhaust in mine, smaller chamber than 243 but same valves,make good power...

These have definitely had work done hand ported, larger 2.05 valves along will what seems to be .030 milling. I'm hoping to find someone that is familiar with MTI racing heads
