Unknown Heads

[FrozenMerc]

I am going through this engine for a customer, and it came to me with a set of aluminum heads of unknown origin.  I am hoping some of you guys can help identify them.  There are no casting marks, and only some hand stamped numbers on each end.  There are geometric features that resemble Edelbrock heads, but no other discerning features.  I am sure they are Chinesium copies, but any help with a brand or manufacturer would be appreciated.

I'm not certain, but didn't someone in Canada make some aluminum FE heads in the mid to late 1990's?

They look like a set of  "Performance World "(Canadian version//Edelbrock knock offs). Othan a laser etched PW on the end of the head there are no real markings on the heads,  snd those obviouslybeingpainted will hide that. I have a new set in the box. That's my best guess....John

Here are some images of the Canadian PW(Performance World) head, sold through Mopac here in BC..  John

Interesting.  Those PW heads sure seem to be a close match.  I might have to put a little brake fluid on the paint and see if there is a logo beneath...

The combustion chambers look better that the Edelbrocks, You'll need to CC them.

The chambers are 69 cc, so for all intents and purposes, I will consider them to be from PW, going forward.
