i took off my heads to find a bent valve, broken spring an rocker, so to not make the whole project a loss i wanted to try and get some more power out of the heads, is it possible to run bigger valves in the stock lq9 heads? i was going to send them out and get new guides and seals, probably a 5angel valve job, but since one is bent i figured id replace them all, i don't want to deck them because im running 8psi of boost and id probably be making too much compression, i was considering a port but it probably wont do much with magna charger intake. any input would be great thanks
