It won't run at all or it runs poorly? You could possibly have your distributor not in the right orientation. Make sure its pointed at 1 when installing at TDC. Make sure your plug wires are on correctly and MAF is plugged in
Would like to know your settings on the timing. Mine runes but pings around 3500rpms. Set the timing to 8 instead of 5 and it’s some what better. Just looking for other info
Thats a decision you have to make for yourself. This is not a LCE cam so it dosnt have a warranty. I would take the advice of the manufacturer because I don't know the specs of the cam you have in mind or if your rockers already have wear on them
Of course the people selling parts want you to buy more parts. If stock rockers are in good usable shape, reuse them. I agree with their remarks about not using reground rockers where the pads been removed. Beyond that, a good set of springs on oem rockers works great.
Lce does have some cams that have fitment issues with stock valvetrain but its not a rocker geometry issue, rather clearance to the guide or coil bind.
