Valve Spring Suggestions
Looking to replace stock valve springs while doing lifters/pushrods and can use any recommendations for which springs to get. Just trying to find comparable to the original stock ones (part # 03911068) or at least specs for them. This is for an '89 5.7 TPI

You can also do 1.6 rockers for some extra lift. They are a bolt on with no modification required. I got Comp cams roller tip 1.6 rockers and did these springs, and new stem seals. You will need the self aligning rockers for the 89 heads.

Cool thanks again!
For lifters are these any good? Again just looking for comparable to stock.
