Thanks. I've already got new rubbers for the plenum to manifold joints. I'll order some head bolts though. Thanks for your help. I've been on three Merc forums prior to this one and they were all useless. Looks like I finally found the decent one.

I'll be using LPG injection, although I'm not sure which make yet. The 280SE has Romano injectors but I'm getting suspicious of their reliability so might try some others.

Will.
