Quoting paul j:
Now that the head is off and heading to machine shop to be checked, is there anything that should be done while they are working on it? I am putting a evo3 turbo on also. If several valves are bent is there any advantage to replacing all of them with something better like nitrided ones or are oem fine? More angles on valve? Lighter valves? Better lifters? Retainers? Several rockers are pitted on the valve end so at least some of them will be replaced- so put in 3g?. Better guides? Slight porting? How about cams? I will have them mic'd to see if they are in spec and straight and if they are bad what should be put back in? Replace head bolts with studs? It is dd and usually don't even get the turbo into boost but I like power when I want it. I am not averse to a little extra power if it is not too expensive but I like durability and minimal maintenance.
Thanks for your views.
How much money do you have? New valves are good, but not needed. 3 angle valve jobs are fine, 5 angle is better but won't make a big difference. Cams are your best power to dollar mod. Head studs are a good investment, I always replace the stock bolts anyway so for a few extra dollars the studs are better. Don't worry about porting, it won't help you out that much. Evo rockers are lighter, and newer, but stock replacement rockers are fine. I'm sure I have a used set in great shape. Yes, get the 3g lifters, they are quieter and newer.
