Marc85Z28 really helped me out here.
I will combine the knowledge:
You have still rough start problems with your Bosch Plugs and change it to Iridium ACF 41-985 (THIS ONEs?) - 5.95 each. Now you dont have problems and your LS1 runs fine. I hope i read it with my not so good english correct.
MARC85Z28 sayd in the other Thread (the link you post), that the more sensible Corvette LS1 runs better with Iridium NGK TR55. There im confused, i found this one: Iridium - NGK TR55IX - 7.39 each and this one Nickel alloy - NGK TR55 - 2.39 each (V-Power Series) and this one Platinum - NGK TR55GP - 2.99 each (G-Power Series).
The reason why im confused is, that no one here in germany have knowledge about that and a mistake will cost a lot of money, because shipping is verry mutch. The Plugs MARC85Z28 are talking about, are Iridium TR55 (in connection with the "GMs TSB 03-06-04-060A"). The only one Iridium NGK TR55 ive found is the first one: NGK TR55IX Iridium NGK TR55IX - 7.39 each
The next problem is, i dont feel good, if i must change with a hammer and distanceplates any spaces or what mean "gapped at .040"? I think i dont understand correctly.
Sorry for my crazy questions
EDIT: I will change the Plugwires too. Must i know something about or can i buy everyone ive find?

Order the AC Delco Iridium AC 41-985 plugs. They are gapped (yes gapped means spaced correclty between the electrode and the ground strap)correctly as they come and will work well for a long time for you.
Any name brand plug wire set will do fine. I use stock wires on the Corvette and 98 Camaro and have Magnecore wires on the 2000 Firebird drag car in my signature.

Jack,
X2 what Al said. I am using the AC Delco Iridium AC 41-985 plugs. They work just fine, best my car ever idle or ran. Also note in the link, the discussion about the Mass Air Flow (MAF) cleaner made by CRC. The stuff really works & you can find whole discussions about it on this message board.
