The heads I have coming have pretty serious springs on them just reading the advert. If I am going to run a middle of the road hydraulic flat tappet cam, at what point is too much spring pressure a bad thing? I do have a set of hardly used 911 Comp springs that are on my 906 heads. I am not going to go crazy with lift, I am looking at this voodoo cam kit.

BTW, I am using Crane gold rockers with 1.65 ratio.

Contact Lunati to see what they require for the cam grind you have & test the springs you have to be sure they are adequate

I reckon your 911s would be fine on that cam with std rocker ratio but could be marginal with your 1.65 ratio.

Just my 2.2c
