I've got a cylinder head stitting in my garage that I was told had been modified.

From inspection the ports have been smoothed and tidied up.

I've pulled a couple of valves out and measured them

The inlet valves are 29.9mm (cam 6502)

The exhaust valves are 24.5 (cam 6505)

I'm pretty sure these are standard valves?

It a leadfree head as well

What spec would you say this head was?

Thanks

1" exhaust
1 & 3/32" Inlet

Thank Ethel, by my calculations that make the standard inlet valve about 27.6mm


So it has been played with then.

Woo Hoo, for sale section here we come!!

Any casting numbers, because those sizes are pretty much Cooper head sizes

Also are you sure on the sizes, those part numbers you give according to somerfords site

6502 = 27mm

6505 = 25.4
