I'm after a big-valve head (valves larger than GT spec 39.5 and 34.7mm) Anyone fancy some extra cash for Christmas?

Anyone?
Me too...
if you already have modified heads that are half decent its not a lot of work to turn them into big valve heads, might be a better option
Hmmm.... didn't think of that!
Anyone on here do the work to make it big valve? Had a price £200 is that fair?
£200 might just get you the parts to do it. I'd expect another £200 labour on top of that.
You'd be better off with a decently ported head on standard size valves than a poorly ported big valve one, my old 1700 race engine made 165bhp/121ftlb on standard size valves.
