Thanks guys. I appreciate the responses.

Greg, the bolt clearance is definitely on the to do list yet. I've found that using allen head bolts and washers work best with SBC headers. You can shape the washer to sit up against the tube better versus using a flanged bolt. The other option that's worked for me are studs with nuts when there's not a lot of room to get the bolt and or socket into the area. For instance, the right side bolts at cylinder 1 and 5 will probably end up being studs. I did that with the headers I put on this engine while it was in my 4th gen Firebird and it worked great. Same thing with C2/3 vettes as some of them can be a bear to deal with when using larger tube diameter headers. Thanks for the feedback and suggestions.
