16V Heads And Blocks.

[shaggy]

Can anyone give me info on 16v Blocks and heads?

My friend has the below items and was wondering what the best ones to use are and what did they come off??

Dave you'll get the engine code off the flat bit that sticks out of the top of the block above the dipstick tube which will tell you which model they came from. There'll be a long number( engine number) and a code ie C20XE or 20XE or 20SEH and so on. The heads look like GM ones not coscast. Should still be ok but I'd get them checked for porosity. Hope this helps.

From SBDs site
"There shouldn't really be a question as to which engine you've got since all XE's are 2-litre - kind of reduces the risk a bit. The block is the same as the eight-valve although there are around five different types with minor variations - cheifly these are in the oil ways and some slight differences in the water passages. However, it's worth checking you haven't got an 1800 block, which should have 1.8 cast into it, whereas the XE has 2.0. There is also a system of casting marks on the top of the block - HH or HG, followed by a number. This corresponds to the block version, i.e. HH1 being the first, these were produced up to HH9 and HG1 being the first of then going to HG4, with each block having improved over its predecessor. XEs have cast cranks and connecting rods although Coscast engines have forged pistons. These have flat skirts all the way round, which is different to cast types. Rev limit on a standard engine 7250 rpm, and bore and stroke is equal at 86mm."
