Default Need bolt sizes

Looking to get some hardware today but cant find the info I need.

I need the bolt size that bolts the crossover tubes onto the heads?

I also need the bolt size for the coils to the valve covers too.

Thanks fellas!!

A search on Yahoo works a bit better than a search on LS1Tech, even though the search turned up info FROM LS1Tech.
