It sounds like its not meant to be doing it of that makes sense when I rev tr engine it gets louder It doesn't sound like a smooth running engine if that makes sense

[jasonmayall]

Get a video up of it?
Sounds like it is the tappets, when they're out by a long way it can cause the valves to open too much for too long, or in your case, if theyre too loose they can stop the valves opening completley causing the noise and a poor running engine.
Its east to fix, Take the rocker cover off, get a 10mm spanner and a feeler guage (.4 inlet, .2 exhaust iirc) but you do have to do them in order.

Do you know what the valve clearances should be?

Sounds like your tappets are fine, sorry I couldn't remember which way round they were...
