What springs do I need with 1.5:1 rockers?

I haven't yet tired fitting my high lift rockers, but I expect there to be coil bind problems....

Whats the deal?

Get the minispares li-lift springs and you won't have a problem with they typical cams we run.
Available in two pundage - 180 and 240 i recall... Take your pick!

yep, 180 is all i went for... not sure about the effect of backpressure in the exhaust, and boost pressure in the inlet trying to open the valves (hence reducing the 'poundage' of the springs however - we'll have to see on that one!
