I'm putting together my cylinder head for my z6. I bought new valve keepers but I guess I didn't buy enough and rather than waiting I decided to use them on the exhaust side and use my old ones for the Intake side. Is this wise? Probably not but I thought I'd ask...

Also, I'm having trouble making a decision on a TB. I'm going to use a skunk2 IM.. would using the stock z6 TB be fine, I can't find a nice oem GSR one... Or should I port my z6 one? Thoughts?

Thanks!
