Iam thinking about buying a LT4 hot cam I have vortec heads with X1943 valve springs good for .600 lift. Are these springs big enough? the LT4 kit uses big dia springs than what mine are.
Anybody know?
Thanks

The hot cam with 1.6 rockers is .525 lift on both intake and exhaust. I would think .600 springs would be fine as long as they have adequate spring seat pressure without being too much.
