Couple of hours if you take your time. fairly easy job so long as you dont drop a valve into the cylinder. Piece of soft rope will be your best tool.

It took me about 6 hours using nylon rope.

Holdenpaedia, they're the brakes Mate.

does changing just the seal achieve anything? If the seals are rooted usually the rest of the head is too waste of time in most cases just like home valve grinds. get the head done up what is your lodic for doing the steam seals just do the inlets if you must if the thing is smokey it will remain so.why dud something up for 4 months

Whats wrong with Melbourne drug addicts sleeping all over the footpath trying to scab money?

An Engine that has been unused for years is a likely candidate for failed Valve Stem Oil Seals. They become hardened.

The rest of the engine can be fine.

only smokey on a cold start.....its fine when hot only lasts about 30 secs till burnt off even when ya put the foot down theres no smoke.thats why i thought just changing the seals would stop the oil from trickling down to the top of the piston

im with hz here, even if the seals are hardened, they will still do their job.
they sit in a groove and stop oil running down through the retainer. they do not break up and cause oil use anything like an umbrella seal does. even when rock hard they only sometimes break on removal of the retainers but often need to be cut off the valve.

if its smokey it will likely be flogged guides. very very common to remove a spring and be able to move the valve sideways in its guide as much as half a mm, which would be approx 010" guide clearance.
