    Default valve spring question

    I'm sure it's been asked before, but I can't find it. I have heard that to run ITR cams you run the ITR intake spring for the intake side (of course) and the GSR intake spring for the exhaust side. Is this true?

    I have GSR head. I wan't to run ITR cams. Are the intake springs in a GSR head the same as ITR exhaust springs? From what I've heard, that's how you do it. So................is it true?

    Its not needed, i have several customers running around on stock GSR valvesprings an ITR cams or even Skunk2 Stage 1s.

    Just keep the Rev Limiter at 8200.

    If you witch to the ITR springs, you can run the revs to 8500.
