TTI's, Edelbrock Heads, Remflex

67 Barracuda, 408 with Edelbrock heads, TTI headers. A couple of questions about this setup.

1) Do the Edelbrock heads have any wet exhaust bolt holes. Do most of you run all bolts for the headers, or studs on the outside bolt holes?

2) I should be breaking in the engine in the next couple of weeks. TTI says they won't cover warranty if you break in the engine with them on. I have a pair of stock 318 exhaust manifolds. Should I use those or just screw it and use the headers.

3) What gasket seals the best with this setup? I have a set of Remflex 6003 (1-1/16" x 1-25/32" Square End Ports,V8 engine, header gasket) but those gaskets have square end ports and the Edelbrock heads and TTI headers have an angle on the end ports, so I have my doubts about how they would seal.

I called Remflex and the woman I spoke with had no clue. After looking at the website, it looks like the 6028 would fit better, but they are listed as MOPAR,V8 - Magnum, For Use With Weld Bead Headers, 318 ('92-'02), 360 ('93 & Newer). Does anybody else use Remflex gaskets? Do yo know what part number.

BTW, my block is a 1984 LA block and the heads are the Edelbrock 60779
