360 build.

motorhome could have had an easy or a hard life depending on loads and hills

Well thats true I suppose. Its been here in the UK for most of its life. Im not sure if that means its had a hard or easy life but generally we dont have vast ranges of Hills it would have gone up. The Roads are so small and winding here that it would generally been confined to the Motorways.

did you do a compression check or leak down before taking the heads off? if not do it

Good point! I'll do that as Ive not touched the Engine yet.

If bores look good you can either leave well enough alone or do a minimum hone and new rings
new pistons without a bore job has been done to get the compression up
use the KB quench dome pistons especially made for LA open chamber heads

Ok cool, a minimal hone an be done at home? Good to know I could replace the Pistions easily if the Bores are good. :) I tried looking on Summit for Pistons but never seen anything like what you're describing.

if it has the premium engine with premium valves and real exhaust seats they are hard to find check the engine codes carefully

Interesting, Ive never heard of a Premium 360 or would know what to look for?

check out the voodoo Lunati line but get your compression nailed down first
at least use the .028 Mr Gasket head gaskets- but you will still have no quench and have less compression than you think you do without measuring

How do I get the compression down? Reduce it or measure it?

Ok, if I get a .028" Gasket set should I still shave the heads?

Thanks for the reply. :)
