Big Valve Head

[Insight G40]

I'm selling my PSD big valve head, bought for my 1W project a coupler of years ago, but I'm in the process of selling all my project bits as I've got a baby on the way.

Collection from Alton in Hampshire.

£500 ovno.

What are the sizes of the valves, is it just the standard BVH with 31mm exhaust valves? (sorry its hard to read the tape measure in the photos)
Thank you.

So does this mean its a 33mm exhaust valve then?

[hayesey]

they look it in the pictures.  The recesses in them and also the tape measure

The inlet looks like its nearly 38ish mm, whats the standard inlet size?

[hayesey]

I would have thought they were standard inlets

Yeah looking at it looks more like 36mm compared to the photo above

Would drop the price a good bit for a sale?

No!

What kind of deal are you willing to come to agreement with then?

And has the head had any work done I.e porting?

[Jezza-7]

I may be wrong but it looks like its been ported. The inlet looks a lot bigger. And the exhaust? Does that ever match the gasket?

[Insight G40]

The inlet valves are 36mm, the exhaust valves are 33mm.

Both inlet and exhaust have been ported.

Yep, it does.
