f303 and 1.7rr

With the iron gt40 heads and the f303 I know these would work great but if I wanted to do the 1.7rr it would put the lift at .542 right? So is it ok to push the limit of the springs or should I use different nonessential or just keep the 1.6rr?

Accepted Answer
It would be better to either get some .550 lift springs or use the 1.6 rr to keep from getting coil bind.
