Cam break in
I was hoping someone could help out with this. I just put a new Summit Cam(285/.456 lift) and lifters in my 70 302, I also put in new valve springs from Trick Flow (115.0@1.700, Open 285.0@1.200, 340 rate, coil bind 1.113). My question is, are the valve springs pressure too much for the cam break in period. I have seen some online videos that suggest that the lighter the spring, the better. I just don't want to screw up my new cam. And the last time I installed one was 30 years ago. Would I be okay with this combination? Thanks.
I also posted this in the 67-72 forum, sorry about that.

In short, the springs should be matched to the specific cam....on the "surface" of what you have published, they should be fine with the cam specs. Videos that you have mentioned, well, I would tend to very much disagree with what has been purported because the valvetrain should be matched and broken in together.
Summit would be the one to answer that question as far as "are the springs appropriate for that cam".......heck, I had one Isky cam that used vascojet (double) valve springs with IIRR 230 lbs of seated pressure and 450 lbs compressed...but that was a lot of cam also.......
