GTV bottom end shells

I have recently put a replacement head on one of my GTV'S after the original plastic tensioner broke up (ouch) Everybody take ten mins to remove you're cam cover and check that you have a metal cam belt tensioner which should be silver and not a black plastic one! mine broke up a couple of weeks before i was going to change the belts and tensioners Any how with a new head fitted the car now runs nicely but i do need to change the bottom end shells just to be on the safe side, Has anyone else done this and are there any tips or knacks to doing it, (all sensible replies will be gratefully received)

You should probably change the shells. Exhaust off, sump off, might be the best way to do it..

I am sure there are different sizes so you will need to measure the crank journals before you buy them.
I think this is due to the differences in tolerance on the cranks.

I am sure someone will correct me on this if I am wrong.
