Exup valve queary

[dudejb46]

Thank you for all you're replies, I've checked and re checked around 3 times and I am 100 sure it's all in order, I've measured each end of the valve and both have very big imperfections at each end to a extent it that the imperfections can't be machined out and still leave enough material,  I've been on fowlers and see that the new valve is 350 odd,

Is there ANY other option for new?

Or

Will any other modes fit so I can broaden my second hand search

Thank you
