input on big SOHC cam with magnum springs

From what I have read, the general consensus is maybe a crane 14 or comp 400 cam is highest recommended cam with mag springs?

Has anyone actually ran a 05 or 07 big cam or simliar on these springs? If so, was there any actual problems like excessive float or broken springs etc?

get the crane spings and retainers, they are cheaper than a cylinder head/engine

yeah, I know what you mean. I guess I was just trying to use as much as possible of what I currently have.... (limited project car budget).

I wasn't even considering the whole interference engine aspect, and that all my work could be wiped out if I drop a valve from pushing the limits of the mag springs. good call.

looks like I will be investing in some peace of mind if nothing else and just buy the crane's.

I think the 07/16 would be okay, I wouldn't try the 005.

are the retainers really needed? i don't see why they would be
