Thanks Guys, I found that the head bolts had been bottoming in the block, probably as a result of some skimming of the head, bolts that had stretched and the much thinner copper gasket. Added an extra washer to the bolts and re-torqued, car is fine now
You can use the compound gasket, but I'm not a fan of it personally, however, a lot of NOS Cu/Ali ones have deteriorated badly over the years, so if you're not going to be pushing the engine hard, the compound type is a reasonable alternative; in my opinion that is . Cheers. G.
Is a thin single plate copper gasket correct for a 1725 engine. I have replaced the cylider head gasket twice and in both cases found water in the oil within minutes of starting up. Gasket was supplied by Sunbeam Specialities.
