If you could please help me out...
First here is the background info. My EJ20G just gut pulled out of my GC8 due to it having low compression in 3 of the cylinders. Turns out my valves were in seriously bad shape. I have one valve that cracked all the way through, lots of others were burnt, a couple went in deeper than others, etc. and the valve seats were getting burnt on a lot of them as well.
That leads me to question 1:
Is it worth getting my heads rebuilt or would I be better off buying a used set of WRX 2.0 heads?
A: If I should get my heads rebuilt, does anyone know of a good place to send them?
B: If I should buy used WRX heads, will there be any issues with compression? Will it require immediate tune?
2: While my engine is pulled, would it be worth my money to buy a lightweight crank pulley and which one? Would that require a tune as well?
I know that's a lot of questions, so I am extremely appreciative of any advice you can give me. Thanks a lot! Hopefully I will be able to help others with things like this later on.
