Converting x-flw to Unleaded
JohnFol - 2/9/02 at 07:57 AM

Has anyone done this? Costs?

So no-one has an unleaded x-flow?

Seeing as no-one answered I can be as vague as I like
Last one I heard was all 8 valves recutting with hardened inserts for £40, this was a "mates rates" job and a couple of years ago too. Gawd knows what it'd cost "with a receipt"...

That's the best answer so far. .. .

I ran an 'unleaded' head for a while but it was an early one with small chambers in it so I changed it for a 'leaded' one with a flat 'chamber' and now use castrol valve master. The head came with the engine (£150) so I don't know the cost, but I think it's around £20-30 per cyl.

UnitWise in Redditch quoted me 80 pounds for X-flow head conversion. I haven't stripped mine yet, so don't know whether or not it needs rebore etc (its been reconned anyway).

i HAVE HAD MY 1600 DONE. BUT I HAVE NOT RUN IT YET. HAD INSERTS PUT INTO THE EXHAUST AND THE HEAD WAS SKIMMED, £100.

Sounds about right. I have a quote of £60 for exhaust or £120 for inlet as well. £34 for head skim and check for seal around valves.

Don't bronze inserts stop the car being legal for the 750MC formula?

"Replacement valve guides may be fitted but only cast iron guides may be used"
