hey to all! ok first post, good ? too. i have started my 7mgte build and i got a ferrea valves 1mm over sized, duel springs, seats and retaners, the good stuff. my prob is will the ferrea lockers mach up to the stock valve guides? i read that stock guides are like a bronze-iron alloy and are fine for big HP, but i went ahead and looked for stronger and or lighter guides. i couldnt find anything for the 7m. also do the rockers ajust valve lash by its self? get back to me when ever. thanks
