well i swapped heads on my z6 with another z6 ran pretty rough it would stop getting gas around 3-4k rpm and i'd have to start it multiple times to get it going. then the other day on my way to work it wouldn't start back up. so i had it towed back to my house it started the next day drove it around the block drove better it'd let me get to about 5k rpm then i took it home wouldn't start back. i've got spark i'm getting fuel. could it have jumped timing? i don't really know what else to check for. my fuel pump works my filter is still getting gas through it.
