my buddies told me to use gm Lt-4 roller rockers for 97 z28 thier the way to go hey said to use thier valve springs also are the LT-4 rockers a 1.6 ratio i dont want to put a cam in it right now so he said its the cheap way to do it is it really worth the time to do this any help would be grateful the car is driven daily its a 6 speed with flp long tube headers slp flywheel and clutch set up aluminum drive shaft underdrive pullys re worked air mass sensor cold air induction accsel igntion moroso wires 4:10 gears so any other bolt ons would be great might go to a 58mm throttle body not to sure yet

 

If you don’t start to use periods I am going to stab you in the ******* with this spork.

From what I’ve gathered from your jumbled disarray of words resembling a communication effort-

you are asking our opinion of 1.6 roller rockers and LT4 valve springs?

Get Comp pro magnum roller rockers and LT1 valve springs, they are a higher quality rocker.

It doesn't matter what clutch you have or what spark plug wires you use.

Don’t waste your money on a bigger TB. It’s been proven time and time again to be worthless till you have serious mods.

 

You can use those springs and roller rockers if you want but there are better ones out there. I wouldn't use the springs either way. Because when you do the cam the lt4 springs are barely good enough for the lt4 hotcam. I'm not sure how much the springs and rockers are. But i would only get those if you were gonna get the whole kit. Otherwise i would just get some cc pro magnums, or some crane gold rr. Then get the dual coil valve springs.

 

crane gold and LT4 HC are the same rockers

 

Oh okay didn't know that. Hey can you tell me the best valve springs to get with the cc pro magnums? They seem to have a few of them on thunderracing.com. My engine has 54,000 on it now should i get pushrods and lifters at the same time? Thanks.
