Best thing to do would be a new cambelt, headgasket and a set of bolts. As the gasket is not actually gone, you should be okay without getting it skimmed as well (although I would check it with a flat rule or plate in any case). Can get the whole lot for well under £50 and is only a couple of hours @ most to change it all.

Then your head bolts have gone weak and are killing the head gasket (common on older CVH models as most are now).

Cheers, seems to be alright since i tightened the head an added fuel treatment and engine treatment!! still smokes a lil bit when cold but should pass emissions, its booked in 2moz for retest hopefully will pass. Then if the gasket goes or starts smokin again, then ill do the gasket AGAIN lol thanks for advise m8
