Some nice things arrived before everything turned to custard

The water passage looks like a shocked face :O

Repco is also delivering at the moment - I ordered a gasket set with the cylinder head but it was a bit bent and some of the sealing material had come away, so ordered another head gasket locally. 

Also painted the water pump pulley a stupid colour because why not.

Fitting tomorrow - what's the opinion on copper gasket spray on head gaskets? New one is a generic permaseal.

Back in April I tried to fit the new head, only to find the dowel sizes from the original head and the new head were different. The head went back on the shelf at this point.

Last week I got the head milled so the block and head had the same diameter dowel holes, and made up some new dowels. New gasket in, then bolted it up yesterday, rockers back in, clearances all set etc.

A workmate also managed to press the impeller out of the water pump and blank off the end, so now I can run electric water pump only, no thermostat and the controller can take care of everything for me. Need to get a very short alternator drive belt now.

Tidied up some other bits, I stripped the rocker cover back to bare metal finish, repainted the exhaust manifold. Looks a bit better. 

Cowl isn't fitted properly- just sitting on there, the gap isn't that horrendous.

Made a little bracket to help support the electric pump, got a bit carried away. Generally the rad hoses are enough to support it, but an extra bracket shouldn't hurt. Speed holes because BOM aspirations...

Hopefully the pump will be ok drawing from the bottom hose in this location. The rad hose should allow for some movement as you're not really meant to solid mount these pumps apparently. 

Time to find some hoses that'll fit. So many things I want to redo. A lot of my previous workmanship (or lack of) is starting to show. Trying to do things properly now.
