That could be bad news if people have had some fail before

Thanks for your input Steve, appreciate your time and knowledge, the buckets pictured are just some stock pics from QED, I believe that I've got Piper buckets but as these were sourced by Phil, I'm not really in a position, nor do I have the inclination, to contact him to ask!!
I'll send you a PM and you can let me know about ordering some from you, grinding them is not a problem, Modus have a valve grinder so it shouldn't be a problem to get the sizes exactly correct.
It makes perfect sense about them being located on the "dick" instead of the top of the valve, Darren had expressed a wish to mount the shims this way also but was concerned that it wouldn't be possible with the shims I'd got from QED. He'll be over the moon with these shims!!

The cams are brand new from Newman, PH5's, as far as I know they have been ground from blanks.
I'm also using +1mm valves, not sure if this would affect the valve clearance due to the seats being in a different position to accommodate the larger valve head. I'm going to call Newman to ask if they've seen this before.

Thanks Steve,
It is correct, you can see the stickers on the end of the cam, brand new PH5's which Newman list as cut from a blank.
I'll pass this extra info onto him and see what the measurements say, he may well have already done this I just haven't got the info yet as he was continuing to look at the head and see what else may be wrong, he is telling me this, he's said he feels something is a miss with the 230 thou for the inlets as he feels this isn't correct and has asked me to do some digging to see what I can find out.
If you did the port boring would that have also included fitting the the +1 valve seats or would these have been fitted by Phil?!?
The way I'm feeling this head is going in the bin and I'll just send another one direct to Neil Roper and start again.

Ah ok, that clears up what may have gone wrong atleast!!
I'll get the guys to check the installed spring length today and as above see how it looks as discussed above, that will give us an indication as to where the problem may lie.
I'll talk to them and see how they feel, it may well make more sense to bring it to you than chase our tails trying to work out what's wrong.
