Need a little more info on the cam. Blowers don't like cams with a lot of overlap and big lifts aren't really necessary. As long as you are keeping your boost in the 5-7 pound range, you don't need high seat pressures

It is a blower cam with 114 lSA. And I am going to overdrive the blower 10% and make 15 lbs of boost.

blower valve springs

The valve spring specs for the cam should be known by the tech department of that cam manufacture, why not just call them. Also if its a street driven motor you probably won't be abusing it to the tune of 9,000 plus like we do drag race motors. If all else fails contact Chet Herbert Cams as they have a long history on Chevy cams.
