Head Gasket

[paulbaker1954]

Hi

I need to change my head gasket and can either buy the OEM one from DS OR I could get the aftermarket set from DS which gives me a complete engine set for same price

And advice on way to go our an alternative source of aftermarket stuff that works

Reason I ask as in an earlier post Trigger suggested that aftermarket ones are no good cos they are thinner and the o rings won’t seal which is the problem I have with an oil weep that is deffo coming from the head gasket level.

Strange as on an earlier build i used an aftermarket set and had no issues

No, i said most aftermarket ones are thicker than oem but, not all

Apologies for misquote

Any recommendations on aftermarket?

OEM, Vesrah, NP, NE with new pucks and measure up all the o rings

Sorry but what are pucks

Yank word for the rubber pontefract cakes that cover the holes neede to get at head bolts between head and valve cover.

Aha that’s like trunk and hood etc, two nations divided by a common language LOL

Thanks Trig, ordered up an NE set from DS. Got head off yesterday and found I had used wrong  O rings on last rebuild looks like they were actually below the level of the head gasket !!

Moral measure twice cut once as they say or more haste less speed.

Next issue is 2 of the threads on the carb float bowls have stripped as I have had the damn things apart that many times. Luckily my local machiner can helicoil them

I've had two CB500 gasket sets and two 550s. The 500 sets have contained the pucks, the 550s did not include them.
