Doesn anyone know if its hard to install 1.9:1 roller rockers and valve springs on an ls1 or is it better to get a mechanic to do it

Now I am assuming you have a stock LS1(Not a L76 or L98 6.0L) but the 5.7L 346ci... Yes, then I think 1.9's should be OK provided the length of the push rods have not/are not being changed as well.

Personally I would have gone 1.8's, Double Springs(>.600lift) and new hardend push rods same length. But if you go for a cam in the future the 1.9's might need to be re-thunk a little as it could cause valves hitting the top of pistons territory on an LS1.

(Disclaimer:- I am no mechanic and what ever has been shown/said here is on your head not mine, so get a qualified and experienced LSx mechanics opinion if unsure.)

Nah I was not gonna get a cam that's why I was hound for 1.9s but thank you for your advice. They reco
Mend new valve springs which I can just look on google on how to insert them and I think you need a special tool maybe

I know for the ecotech you need some spring clamps to get them out, I'm assuming these will be the same for the ls1, do not hold me to this.
