I just ordered valve springs and retainers from TA performance. These are for a Buick V6.
Original Specs TA specs VTA1435
1.3125 spring diameter 1.360
1.8125 intalled height 1.860
115 lb valve closed 100 lb
315 lb valve @ .500 315 lb
both springs have an inner damper
retainers are correct dimensions
Considering the input I have received, I think I have made the right decision.
Thanks
Warren
