Valve Spring Pocket Size ?
Does anyone know what the largest dia valve spring that factory 416 or 041 heads can be machined to fit?
I have a set of each of those heads and I'd like to use one of those sets, along with some larger dia springs if possible.
Thanks

As usual, ede is right. I don't question him, but n case you do, here's some evidence. The last set of 14014416s I worked up were opened to 1.480", and there was room for a lot more spring if necessary:
