    valve seal and spring replace

    i am replacing my valve springs and valve seals as well as spring locators the problem is that the spring locators I.D. are .570 and the stock guides are .500 so they are loose by .035, i called comp cams and they said that that combo is the only thing that they sell for a LS1 and that no one has ever called about this problem. Am i missing something here?

    I will be removing my comp 26918 springs and installing the comp dual spring kit, maybe this weekend, so I will be checking that out... What spring kit are you installing ?

    i am installing 26918 springs on stock heads and guides.

    I just got off of the phone again with comp cams and the guy said he wouldnt run Comp Cams springs with Comp Cams spring locators on a stock LS1 head, that i should get the original seal and locator that are one unit or just deal with the .070 movement??????? WTF

    Are you talking about the seat that goes on the head first, then the spring ? I'd use the stock seats. The retainers on top, should be ok.

    I'd just re-use the stock locators / seats.

    I would upgrade the retainers & locks, to titanium, for higher rpm's.

    the stock locator is part of the seal, you cant "re-use" that part.... so are you saying that my only option is to replace the original seals with only a GM part from a dealer?
