Head Casting Numbers

[M_Pied_Lourd]

I have three heads for my TR3A with three different casting numbers.

B180

P39

E204

Is there a significance to these numbers?

Cheers,

Yeah, they were cast with different molds.

Ba da boom.

Seriously, the best treatise on TR head variations I know of is at

Thanks Randall,

That should help me out to identify what I have.
