Some questions about aftermarket valves
So I took the valve cover off my 06 GTX to find that I have the bad valves, so I have decided to buy Ferrea valves, and also upgrade my valve springs.
First question is do I have to get a valve job or can I just lap the valves in?
I would like to get everything done in a week so I do not miss the weekend, here is everything I am going to buy:
-complete set Ferra valves (intake and exhaust)
-Riva head stud kit
-Riva pro series head gasket
-Riva valve train upgrade kit
-OEM intake and exhaust manifold gaskets
Am I missing anything?

Should replace the rocker shaft bolts too.
I can't remember if they come in the riva valvetrain kit?

You do get new rocker shaft bolt in the Riva kit

The Ferrea valves will just lap in. No machining needed.
Don't forget the greenhulk coupon code in the forums store to save yourself 10% off the Riva parts

no its not just a matter of take out and put in, they have to be lapped in with a lapping paste im pretty sure

Unless that engine is really low hours. Its advisable to have a valve job done when you do all that. I sent mine off over the winter and had it all done at the same time.
