This is just one way to do it ( of many I'm sure )
Liners first, sealant on the base gaskets. Torque plate on ( or cylinder head ) torqued to 75% of spec. leave overnight.
Next the cam while I can still get my hands on it so I don't nick anything, fully lub'd.
Crank & rear main seal with a little silicone sealant left overnight so as not to disturb it.
Next day rods/pistons, time the cam, oil pump, pan, tc tensioner, cover, balancer, lifters ( +more lube), head....in the car it goes.
Pushrods & rockers last.
I have managed to get lifters back in their bores with a magnetic retriever through the pushrod tubes but I think it was more luck than skill.
I only had to do it once, lesson learned

Subject: [Fot] Engine Building Tip Needed
On a TR4 engine build, I usually install the lifters and head as soon as the liners w/pistons and rods are seated in the block. I like to flip the engine upside down on the stand to install and torque the conrod caps but the lifters will fall out unless there is a way to hold them in place. I could install the rocker arm assembly and pushrods before flipping but I need to rotate the crank to set a nominal lash and risk nicking up the crank journals.
Has anyone seen or made a gizmo that holds the valve lifters in their bore when the TR4 engine is turned upside down on an engine stand and the pushrod and rocker arm assembly has been removed (or not been installed)? If the lifters fall out, that would means cylinder head removal. Certainly Kas has had to deal with this delimma in his TR engine building
experience. What is your trick Kas?
Thanks
