They're taking the piss as usual for them.
Plenty of heads around even whole engines, head wear is n ot an issue normally on these afaik, my mk4 escy had over 250,000 on it, head never been off, only head work was the usual tappets/shims.
You will get a better price/service at Randalls, 01359 251888, ask for brian or barry, do all machining even have engine dyno's, repro cams etc, the place is a goldmine of engine stuff, brian reconned the engine in the ark ha ha!!, no he's just old but seriously knows his stuff, puts loads of work money his way the last 15 years or so.
