Just got my head back from being skimmed,new valve guids and bits and now I seem to be missing the 2 white semicircle rubber bits from the back of the head any one know where I could get some new ones?







And could someone tell me what all the numbers mean?

Can't seem to find them they are not the ones at the front that are red they were white and were at the back of the head.

Looks like the head has been line bored at some point. ????

Chris 82

Never heard of line boring?

It's from a rouse sport 304r not sure if that has any thing to do with it, perhaps I'll have to ring the machine shop and see if they can find them,

Line boring is where the camshaft bearing surfaces with caps are machined to keep then inline.


Like I said never seen a yb head like that

Hopefully they can find them as I've no idea where you could get replacements?

The machine shop might know of somewhere that supplies bits?
