I went ahead and got this.

Ferrea Competition Plus Standard Size Valves
Supertech Dual Valve spring(100lb), Titanium Retainers, Spring Seats, Valve Locks

I think that will do me. I am going to try and get the head pulled apart this weekend, and should have the parts end of next week, so I can get assembled and finish up the motor.

When I did my first I had the surface decked, valve job, IP springs and retainers, Ferrea Valves, Vavle Seals, hot tank, bead blast, gasket matched the intake and exhaust, deburred the runners, closed off the secondary air injection ports, had the cam bearing checked. The one thing I should have done that I did not do is replace the valve guides.

I would have to guess that the entire labor bill was around $600 but that has been some time ago.

Appreciate that. I didn't order the seals or guides this time around, I'm going to see how it looks when assembled.

W//the amount of boost I'll be running, it should seal pretty well, lol.

I've been told by a few different reputable people that w/the low mileage on the head, it shouldn't be an issue.

Guess we will see.

As for the stock f22 head ...your plenty fine revving to 9k. I've been doing that for 30k+ miles with no issues. I guess they have upgraded valve stem keepers and retainers over the f20. I'd have to think 9500 isn't out of the question considering.

I felt the same way, the more I've learned, BUT w/the added power heat/etc. If I had a mis-shift, or something were to happen, I feel confident I won't grenade a motor over dropping a valve now.

Cheap insurance imo, plus I can rev it out, which is nice.

Ok, I'm sure there is a reason this is dumb, but why not change your gearing? If all you are after is fewer shifts, up the boost and put in a different final drive rearend. Or switch to an AP1 transmission.

I bumped my f20 to a redline of 10,200 because when I do shift I want it to be higher in the rev range while entering the next gear. The higher the rpm's in the next gear the higher the hp/tq. in my case anyway.
