Speedway Motors has a lake style header kit that you weld up yourself for a BB Chevy and was going to order. Does anyone know if they come with the holes already drilled or do you have to drill your own?

holes drilled in what????
Bearcamp,
If you're talking the holes in the megaphone you'll have to cut to fit, depending on how you want them to look. Instead of the "kit" I bought the megaphones from Speedway, and then bought seven or eight 1.625" J-tubes from Summit. Mine was a bit of a special case, as I did not want to cut my splash aprons, so I had to custom fit the primaries at decreasing angles to follow the megaphone angle. You can see mine in my build thread, about #57 http://www.clubhotrod.com/hot-rod-bu...3-build-4.html just for a point of reference.
Talkin about the holes in the megaphones. rspears,,,,how tough was it to get them right and what did you use to get a good cut?

I'm OK with MIG, so I tacked it all in place, then carried them to a kid who has his college degree in welding (ASME Inspector) and he TIG'd them for me. I talked to the guy at LakeHeaders.com (CRS has his name blocked right now.....) and he really helped me get a handle on the process. For a basic set, straight off the heads, he can probably make them for you pretty cheap - http://www.lakeheaders.com/Home.html
