Aluminum Roller Rockers

yeah, I'm planning to run a solid roller camshaft, unless someone comes along and convinces me otherwise. This is my plan so far:

-D0OE fully ported, 1.94/1.60 valves, guide plates & studs
-302 +.030" bore, ARP rod bolts, fully balanced
-Single plane intake + holley carb
-Solid roller something like a Comp 294s (248* @ .050" lift)

Comp cams reccomends their 986-16 spring set which is a dual spring with the following specs:

296 lb/in overall rate
132 lb pressure @ 1.750 (seat pressure)
280 lb pressure @ 1.250 (open pressure)


At this point, I have not purchased anything except the valves, intake... I'm trying to figure / plan everything out and then I'll start ordering all the parts in the next week or so.

Will I have any problems with a cam / spring combination like that while running these rockers? What would you say the maximum open spring pressure should be with the Angus, Scorpion, and Harland Sharp rockers should be?
