WAY better gaskets than the local autoparts store! If you have to go gaskets, go with these. I had leaks after leaks, using the local store's gaskets. Even their upgraded one's didn't last too long. I switched to these gaskets, by Z1, and they've outlasted the local shops 10 fold. Unless you V-band, you're gonna eventually get a leak! Especially when you're shooting flames, 2 stepping, anti- lagging, etc., which I do. Thanks to Z1's awesome tuning! (Thanks Jon!) But these gaskets hold up really well. Worth it!
