Do the exhaust and inlet have to be tensioned at different positions. Thought they had to turned down about 3/4 of a turn after tension reached. But maybe I'm thinking if single rockers.
Also thinking of doing the springs as well ( got a set of Crow replacement). Anyone recommend a good spring compressor. Found one in US (LMT) but not sure which one I need. Sold here at Outlaw Speed Shop and are around the $380 mark
Have not replaced lifters before, that's why the questions.

If the lifters are the same dimensions as the original lifters (and they should be), then no adjustment needed.
If the height is slightly different, then you might need to farnackle around with shims.
Wind them down about 0.030" preload.
TDC is is what you want, otherwise you won't get the lifters out on the corners.
Grab one of these for the springs -
