With the head back at LCR, it needed to be assembled.
240Z's came with an oil 'spray bar' that bolts to the side of the camshaft towers, that sprays oil onto the camshaft lobes.
This is a poor design as the tiny tube and orifices' can easily block up with gunk and worse, the bar itself can fracture over time & fall into the cambox...
Nissan fixed this later in the bigger 2.8ltr engine (L28) with an internally oiled camshaft.
Thankfully Les had enough junk L28 heads in stock, so the cam towers from one were used on the E31 head, as they are a direct swap.
Because the top and bottom head faces had been decked, a set of cam tower shims were installed to bring the camshaft 'wipe' back into the correct geometry.
Next a suitable camshaft was fitted. As the engine is relatively stock, we didn't want to go to wild.
The grind is from Clive Cams, and is a direct copy of a Wade 733a. It's very very mild with just a tad more lift and duration over a stock grind cam.
Unfortunately the original valve springs were worn out so a good set of used L28 valve springs were installed, along with new thicker lash pads/caps and refaced rockers.
It was all reassembled, checked and pronounced good to go - it's almost a shame to put the tappet cover back on!
The tappet cover was also given the Hydro-blast treatment.
