n e one got the part #for stage 8 bolts aluminum gaskets? for my 1991 z28?????????and cat adaptor

 

The bolt P/N is (Summit) STG-8911A 1" long (same length SLP would sell you) $43.95...Gasket P/N Percy's PHP-66012 square port $34.95 (also Summit)...Earl's also offers aluminum gaskets, but I'm not sure which one is correct for your heads (1.36"x1.36" P/N EAR-29DB3B or 1.50"x1.50" EAR-29D03B - Summit) $34.99...SLP cat adapter 3" slip fit P/N 30038 $34.95 (SLPonline) Hope this is what you need.

 

I bought all of the above and still have a header leak at number 5 cylinder. Not to mention headers rubbing against steering column and burning my spark plug boots. Do your self a favor and buy the cat adapter and bring it to your local muffler shop and see if they can make you on identical for cheaper then mail it back to Summit. I did that and the guy at muffler shop didn't even charge me. SLP is a frigin' rip off. i've posted this in the past I'm not happy with these headers at all

 

u sure i need 1'' bolts?

 

That's the length SLP offers individually (not in the install kit), but you probably could use STG-8911 3/4" long $37.95. I think either would likely work.
