Header Gaskets
I was told by the man that is going to install my headers that the gaskets that coem with the headers to install them are no good. he said that the gaskets they give you will start to leak rather quickly.
I ordered SLP headers... are the gaskets they give no good? If not, thats fine - but which should I get?
Also, exactly which gaskets am I gonna need to install SLP 1 5/8 headers and the SLP Y pipe on a dual cat car? I am most likely going to order gaskets from Jeg's. What size do I order to go with my SLP 1 5/8 jet coated headers and going onto my stock L98 heads? Which locking bolts should I order?

Within a week my gaskets on my SLP headers leaked like crazy on one side but not the other. I went with felpro and it solved the problem untill I cracked a head, then after replacing the heads I went with the SCE copper gaskets and have not had ANY problems. They are probably overkill for street but they hold up real well.

My SLP gaskets havent leaked yet,only been like 3 weeks though, but pretty good considering the two end flanges aren't even flat on the driver's side...
