I've got a 86 Firebird that I just lined my transmission out on and now I'm ready to change my valve springs. Its a LG4 with a XE 268 cam and I've got the valvesprings that match it. What would be the easiest way to change them? Or do I really need to change them?
Thanks

 

yes you need to change the springs, lifters and timing chain.

 

I all ready replaced the lifters and timing chain. I just wonder what would be the easiest way to change them. Take off the heads, top dead center and use a on car spring compressor or use an air hose. We actually rebuilt the motor but didn't have a valve spring compressor at the time and we rebuilt it outside in the middle of winter so I wanted to get it back together and in the car as quickly as possible. And would it hurt to drive the car with the stock springs for a few days if you take it easy on it ?
Thanks

 

I don't have a air compressor so I jam 3ft of 1/4" nylon rope in through the spark plug hole and rotate engine around until it locks the valves in place.
No worries about power going off or someone tripping over the air line while you have a spring out

 

gaskets are cheap enough, just pull the heads and use a C clamp style valve spring compressor.


doing them on the engine is no fun.
