New camshaft install questions

I looked at the spring pressures closed and open, and yeah, these have some fairly high pressures, higher than my personal limit for break in. But this all depends on the installed height, and the info for that is not in the original post.

Why not take an outer spring down to your local machine shop and ask if they can measure the rate, or, alternately, measure the spring pressures at both closed and fully open heights?

Are you using non-stock retainers and/or longer valves? I hope so because the stock installed spring height on stock type heads is 1.650" and .525" lift would yield an open spring height of 1.125" which is .050" SHORTER than the spring bind height of the 924-16 springs. These springs look to be made for a taller valve/retainer combination:

Or are you using the beehive springs? Need more info on heads, valves, retainers, etc.

BTW, BE SURE to use a moly paste type of cam lube for assembly!
