96 LT1 valve spring pressure

Rob Petrie E395 · 11-12-2017, 08:25 PM

The heads I have (96 LT1) I bought used. They had the Howard's Springs on them when I bought them. I have the PAC 1409X on it now. They are probably better but I can't say for sure one way or another. I have something wrong somewhere in the car and can't figure it out. Wish I could be more help.

I'm at 180 on the seat.
