do yu mean cam - or rocker shaft?
The camshaft has nothing to do with the cylinder head.
It is way down in the block.
The man asked you if you were needing a complete cylinder head, with valves, rocker-shaft and rockers.
You're thinking of the crankshaft mate.
The camshaft sits at the top of the head, rotates and fires the valves off in sequence.
What your calling a Rockershaft is a Camshaft
OK, OK, put your dummy back in.
Only had it for 5 minutes, barely had time to look under the bonnet.
Still after a Cyl Head if anyone got one for sale??
PS - a few of us are waiting for the "sorry" word
I modify heads.
A second head means the vehicle is off road 2-3 hours rather than a week.
