First Camshaft/Valvespring Install on LQ4 --------------------------------------------------------------------------------
Installing an ls1 hotcam kit /w the ls6 valvesprings in a 2005 lq4 6.0l truck motor. The ls6 springs came with some valve seats that are different from the lq4 ones I have. The ones in my engine contain the seal while the ls6 ones have a separate seat and seal (seal not included). From taking some quick measurements, I think that the installed height of the spring will be the same with either seat (around 1.805 and the install height spring recommendation is 1.801). Does that mean I can just use the stock seats I have, swap the ls6 springs in without any shims and call it good? Anyone know where to find stock valvespring installed heights for the 05 lq4 to back up the measurements i took?
I really appreciate the help!
