Valve Springs

What are good springs above the stockers? Thought I would go ahead and take care of this.

I'm using the stock 75lb replacements from T/A with the cups but most use comp 980's.

Comp 980s here, no problems at all.

How many miles are on the car? I replaced mine at 170k and ended up wiping out the bottom end lol...

Right now, about 126K. Probably had 105ish on it when they went it. They've been in there a while.

Are or were you using zddp?

 

[87Turbo-TWE4]

The odo says 28K but I believe it to be 128k (no documentation). Compression test showed fine. I seriously doubt it has had any zddp in it ever but I changed the oil using VR1 and a bottle of zddp.

New stock replacements will work well for a stock setup. Sealed-Power VS-744 available at local parts stores.
