Jumping in late:
If its hydraulic then lash the valves to zero or .002" of lash.
Lifters will pump up solid and should help.
Turning springs by hand does not sound good.
We don't know what the camshaft is but I have an old Reed book.
I will check tomorrow and see if we can find a cam that fits your description.
I would NOT put 1.6 rockers on it unless you know how close your springs are to coil bind now.

matt, I got a dial indicator yesterday and removed the rocker and checked the lift at the pushrod as best as I could, intake .322= .483, exh..324=.486......if you find it in your book I would really like a copy of the page etc. thanks bobby

Bobby:
The only Reed cams book I have is a listing of master lobes. I used to have a late 80's catalog and loaned it to someone.
You can guess that was the last time I saw that book.
The best match I can find in the listing of lobes looks like this:
.320" lift matches a lobe with 242* @.050". Didn't see one with .322" or .324"
Most oval track cams that I'v seen have a 106* lobe separation.
Good luck: Matt

BK:
If this is a "race motor" why hydraulic lifters? Make sure to check piston to valve clearance.
