Thanks mate. as soon as I finish the carby job, I'll get to the lifters and the cams, camshaft.
Only problem I remember was, that the idiot who welded the cracks and machined the head, lost few washers that goes between valve springs, he gave replacement ones, which weren't the right thickness. So, it was putting slightly extra pressure on one or two of the springs. I can't remember which cylinder it was, but as soon as I open the rocker cover, I'll be able to see it.
Was it a good idea to use the 'bad' washers he gave me?!!

P.S. I had to take the head back to him again, 'cos he missed one of the cracks, a pretty obvious one. Embarrassing as it was, it was my GF who noticed the crack, 'cos I was too busy trusting the fella. I knew he was bit of a dud, but didn't have a choice 'cos there was nobody to do the job during x'mas holidays. So, the head had two lots of welding and machining in two days, but didn't have to over machine it though, 'cos I checked the thickness. What I dunno it whether the extra work has weakened head or not.

This escalated quickly .... The post was about a ticking noise now your talking recon'd heads. I wouldnt bother with replacing the head until you need it mate. I just did a recon head on my RB30 patrol, the cam, rockers etc were reused but were bathed in cleaning fluid and looked mint but still tick. It is really common with RB30's,, they just get a bit sticky and tick when they open / shut. When the revs are higher there is more oil pressure around the lifters so they are better.

Exhaust is definitely worth looking at aswell as mentioned!

Ok. Cool. Thanks for the advice mate.

This problem sorted out itself without having to do much from my end. I think the cooling whether had an effect?!
