evo3 head vs. 1g head

[4seasons69]

the cas is definitely different than the one on my 90. I'll take off the intake manifold and look at the intake ports and see what they look like. is there anything else that could verify that it's an evo3 head like any markings on the cams or anything? thanks for the replies

well the intake ports on the head are definitely the same as the 1g intake manifold. it also doesn't look like it's been machined to port match them either. is it safe to say this is actually just a 1g head??
