any spring recommendations? It will be under .650 lift even with the 1.7. if this will/has worked I would be using quality nsa rockers. anyone doing this with a high lift cam? worth it? the heads I want to put on flow 292@ .650 lift

 

I am running a 1.7 NSA rocker on a small basecirlce custom grind with .624/.628 lift. I have not experienced any issues as of yet.

 

what springs/ installed height? is this a hyrdraulic cam?

 

Springs are pac 1218's, stock height. And yes it is a very aggressive xfi lobe with a HR, plus its a small base circle.

 

Who recommended the cam to you? I know that the xfi lobes are very aggressive lobes with just 1.6RR. I don't think there are any springs that will work with that setup, not to mention your valve geometry will be off.
