    505-16 is rated 3.0 out of 5 by 2.
    Rated 1 out of 5 by from I had issues When pressing them on the guides, I ended up pushing the center out of them. It almost seems that they fit 11/32 stems instead of 3/8

    Will these fit a 1969 chevy 396

    Asked by: Andy69396
    You will want to measure to be sure that you valve guides are 3/8", but most big block Chevy engines are.

    Will these fit without modification on a stock 1974 360 LA engine? But if so, what is required?

    Asked by: JPaul
    Yes, these would be the recommended valve seal for your 360.
