valve seat recession or poorly set up gaps???

It was acting like a kangaroo on fri morn,and I had to get a lift into work!
While fitting the new fuel pump this morn,as I eventually diagnosed fuel starvation, I found the feed pipe partially blocked with a dry almost solid lump of crud!
I suspect this may have been floating about in the reserve pipe,as I had to use it last week,or it was it the res/main tap area,and must of got sucked thorough.
The performance feels better,and when floored gets up to 60 in 2nd,changes up then still feels like its accelerating but needs plenty of room to make it above 70,so am going for a 15mile blast up the motorway to see what it will do.
Also re-did the compression test,as I suspected my testers valve was knackered,using mine it shows 95 dry,110psi wet, then using my neighbours one it gave as near as damn it 175psi across all 4 with a little oil in the bore from the previous dry/wet test.
All other bits,cond,cap,leads,rotor etc have been swapped 1 by 1 and make no difference.
So even though some would say its current performance is what to expect,the little extra oomph it lacks at higher speeds has got to be down to the valve gaps all being a bit on the tight side.
Got to get the V8 up and running again as it doesnt like being left for more than 2 days,"something in the carb sticks??",then I can take the 2000's cam off to reshim.

and when you take them out ... put them back in the same order, there is one thick one and one thin one. I forget which goes on the top/underneath, but do it as per the book.

The thin one always goes on the bottom, (ie directly on top of the valve stem) with the thicker one placed on top of it. If you think about it it couldn't possibly be the other way around.

The single shims were fitted to late engines then?
Because i have come across these too...

No, the single shims were on the early engines.

What year does early end?? and late start??

Don't know, and it won't be years it will be by engine numbers, but you can use singles, or thin/thick pairs as you need them in any engine.
