wanted: big-valve xflow head

[pablomills]

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

[pablomills]

Anyone?

[Jack1995]

Me too...

[Graham]

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

[pablomills]

Hmmm.... didn't think of that!

[Jack1995]

Anyone on here do the work to make it big valve? Had a price £200 is that fair?

[rollerrocker]

£200 might just get you the parts to do it. I'd expect another £200 labour on top of that.

sounds cheap

sounds a lot

.
but a lot would depend on what sort of head/spec you are starting with

[Pushrod King]

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.
