TU3 cylinder head types?? Z04, Z05, Z07 etc

Recommended Posts

Posted (edited)

So..... bear with me in this one.


I am wanting to get a cylinder head for my 1989 TU3-K1G engine


Ive upgraded to a twin choke solex from the standard single and I’m now looking for a cylinder head to play with.

I am after one which still has the water ways in for warming the intake manifold but which also has the large camshaft bearings so I can put a Catcams 602 in. Or maybe a 645 if I’m feeling it?? 


Anyway the plan is buy an old head. Skim it, port it, maybe a little larger inlet valves, new cam and maybe some other goodies. 


I’ve done lots of googling but for life of me can’t find out what all the differen “Z” numbers mean.


My head doesn’t seem to have a Z anything on that I can see. 


If anyone has any ideas which head in after I would greatly appriceite it.


Thanks Tom
