Looks like good fun. Spanner candy! I always enjoy putting a nice clean engine back together.
A propos of nothing more than idle curiosity when enlarging the photo of the head it appears that the pushrod seals (dished washer, rubber collar & flat washer) are still in place. You will of course be replacing the rubber collars?
The pattern rubber collars soon become as hard and brittle as Bakelite with heat which leads to oil leaks. I and many others have used a suitable number of Nitrile 'O' rings instead which don't harden and work very well.

Photo of suggested 'O' rings and the original rubber collars.....

In this photo the (greased) 'O' rings are in place but the essential dished washer isn't shown but will be fitted.

Yeah, I have the seals ready and may try the oring trick, in fact you can see them (upper right corner of the work bench photo)
