I have picked up a tick back near number 7 that I am almost certain is a header gasket blown out. I checked and all the header bolts were loose and I could see some black carbon around that port. The tick changed when I tightend the bolts but is still there and more intermitten... Anyway, I need to change the gasket. I bought this car so I have no idea what is in there now, but I am assuming it is the ones that came with the Doug's Headers. I have the following questions:

1. What are the best gaskets to use with the aluminum E-heads and Doug's headers?
2. What bolts would you recommend?
3. What should I torgue the bolts to on the aluminum E-heads? Do I need to use sealant or thread lubricant?
4. Are the bolts in the water jacket on the e-heads?

Thanks in advance....
