Valve Spring ?

[clonestocker]

My son's motor has a 160,000 miles on it and he is putting some upgrades on it. I'm sure the springs could use replacing. What valve springs should be used as a replacement for stock springs. The motor at this point will still be using the stock cam. thx matt s

I went with Comp 980's a few years back and have not had any issues. Still same stock cam.

Just use stock replacement springs. I wouldn't go with higher pressure springs on a stock motor with that kind of miles.

I changed mine years ago with LT1's and thinking of changing again. This time I may go with Kirbans 40.00 set.

if your going to do that i would lakso think about installing some new bearings in the bottom end.

My reasoning for this is now that you have good valve springs it will allow the engine to rev harder and higher along with them not allowing boost to blow open the intake valve so you wil have higher cylinder pressures.

HTH.

BTW i used the LT-1 chevy springs and have not looked back.

SloGn,
My son put new rod inserts in, when it was down. What are the choices for replacement springs? thx matt

 

[SloGN]

i would use the chevy lt-1 valve springs or check into the new style bee hive springs.

SloGn,
Do you use the stock spring retainers with the LT-1 springs? thx matt
