I'm gonna put some valve seals in my little 70 Firebird. I've never did this in the car on as assembled engine before. I assembled a set of 6x heads a year back, basically stock, I just put the Fel pro seals on and the Fel pro little o ring on the valves. the engine runs awesome, I broke it in January. Anyway, an old friend stopped by the other day and said I may have to cut them. Cut them with a cutter? A valve seal cutter? I have not been able to get a hold of him the last couple weeks for him to elaborate. This guy has built hundreds of engine and been a hot rodder since the late 60's. So what's the deal do I got to cut them? I didn't on the 6x heads. I haven't dug up much on it.
