Alloy head

Have I missed something... did none of the commer PBs come with the alloy head engines as standard? If not what were they from?

I'm having problems getting the correct gasket for the highwayman. It's got twin strombergs...

Alloy heads were fitted to cars like Rapier, Alpine, Hunter, Vogue etc.

Head gasket sets usually state whether they're for iron or alloy heads.
 
Fitting the alloy head engine may have been a dealer option but not a production one. As Baz says order one for a later (twin Stromberg)1725 Rapier and all will be fine:)
 
If it's an alloy head version head set then yes it will fit. Are we talking head set or engine that you have?
 
Well it's a alloy head off my highwayman. Which has the twin stromberg'd engine. It came as is. Running. However not very well. The old gasket was so mangled after removal i'm struggling to compare it you see.

After fitting a gasket for a cast iron head I had sitting about - that didn't hold :oops:

On closer inspection there is quite a bit of pitting so it would seem the heads going to need some welding too.

Fun and games!
 
I think the actual shape of the gaskets is the same, as it's the same block, but the materials they're made of is different - the inlet and exhaust ports are completely different though. Have you got a pic of the damage to the head, you might get away with a good skim.
 
the outlines of the gasket are from the iron head one I incorrectly fitted - which did have different shaped apertures, smaller in places... the guy skimming the head thinks that a few of the deep pits sit outside the chamber with the 'correct' alloy hunter gasket I've got now.

Not sure yet, might get it back today.

On another note I was studying the workshop manual and noticed on an exploded view of the engine 3 sleeves sitting between the head and the block I'm guessing on water ways? These weren't present on mine on strip down. Should they be?
 
Phew, I thought that was the head after skimming and re-use:oops:
Not sure what you mean by the sleeves, cant find a diagram with them on
 
haha yes I would be worried then! Fingers crossed it's not too bad after the skim.

To be honest Panky it's on my older manual for the 1600 engine. The correct manual for the 1725 doesn't show the same illustration - just wondering if they are there or not...
 
hello, may well be. I was just concerned what with all the pitting they kept the water in the water ways rather than spilling between the gasket!
