Hey all. I'm new to the lt1 and I'm putting one together (on a budget) for my '95 T/A and I'm curious how large of diameter valve springs I can run without adding work. I see that the lt4's are like 1.33 as a direct replacement. I'm looking at a set that are 1.465 OD to handle a bigger cam. Will I have problems with that? Head casting #1028374
Thanks in advance.
