Just trying to save you $100 and some compression, because bigger valve reliefs equals less compression which is what you were looking to increase in the first place! |
no the timimg chain was installed along with the checking springs, and i rolled it over by hand....the intake is the only one that hit. it just barely touched on both sides of the valve relief, so if the relief was just a little bit wider it woulda cleared. but ya its really a bummer, how much compression do you think ill lose?
