Reminds me of the time I needed to fit some new guides to a pair of heads. The night before I managed to slip the packet of new guides in the freezer, under a bag of peas.
Management was due to go out the next day, careful measuring revealed that if all the shelves and sides of the oven were removed a Rover cylinder head would go in and be able to be heated to 250 deg.
Trouble was, there’s a lot of guides, and the heads needed returning to re heat, and time dragged on, and well….
I got caught !
You didn’t actually mention your outcome ?
