Early heads v late heads - differences

Post by bstardchild »

Would this be any good for a E reg Coupe S thats dropped a valve or two?

I'm not sure what the differences are unless the seller means non-hydraulic tappets :shock:

Yes that the non-hydraulic head, some people on eBay are useless with item descriptions

"rocker-finger" seems a perfectly adequate description of a mechanical head to me. Im not sure if itll work as the bottom ends might be different as well (weaker oil pumps on earlier ones possibly?) stuff like that. You can see from the pics anyway, the E-reg one will almost certainly have hydraulic tappets, my C reg has em. :D

Also looking more closely the valves are recessed quite alot into the head, the coupe s head shoud be virtually flat. so some compression points would be lost if you fitted it.

its funny you should mention that Gareth.....

..... would have been interesting to see what compression you got with your original 1.4 engine.

the fuel pumps are also different between hydraulic and mechanical heads.

yeah I was thinking that today. if the GT inlet manifold fitted then that would have almost solved most of my problems. I just wonder if a GT cam is compatible with a mechanical head. :D
