1.6 RRs on 93 vette heads...
Allright, i got a set of 93 LT1 vette heads, ported them and was wanting to get the most from them by going with 1.6 RRs, my machine shop(a verry good one) that i use told me thet with the ratio on the lift the stock springs would coil bind right at the max lift, anyone just strap some 1.6ers on their LT1 and not coil bind or have any issues or is a spring change a must?

This way you have a spring rated for a .570 lift cam and get the added advatages of the light weight spring/retainer package. The installed height will match the LT-1's without having to use shims or machine work to the heads.
