Why don't my valve seals fit?
I am rebuilding a set of 461 double hump chevy heads and bought umbrella valve seals to put on. I went to install them and it turns out that they fit the valves but hit then the valve springs will not fit over them. They hit the damper. Any idea why? Did i get the wrong ones? These are for a 327 and I think that is the engine these originally came on.
