Cylinder head identification.
Posted: Wed Nov 11, 2020 9:16 pm
Not sure if anybody has any ideas but i have a V8 3.5 Ltr rover in my 62 Ford. The Block engine number is identified as a sd1 Auto 9.35:1 and the heads on the engine aren't Sd1 heads by the looks of it.
The heads fitted have casting number 12A then BIRMAL and 612571.
I also Have a set of What I have been told are Vitesse heads these have ERC0216 then 7E652 and have a number stamped on the end 6895. These definitely have the bigger ports and rim flow shaped valves. Also have a casting mark which looks like a stick man.
Ive added images of these.
The final set I have are stock 0216 Sd1 heads these are definitely SD1 heads. Any help identifying the others would be appreciated.
The engine runs but not knowing what the heads are I have no idea of compression ratio etc.
Cheers Nigel
