TR 55s and double check gap.

You can't be 100% on the old plugs and if they are all already out might as well put in somthing you know is healthy.

anyone using bosch platinums, not the +2 or +4, just the regular ones? i've heard good things but wondered if anyone used them on ls1's.

Yes I had a set it my car and after around 6 thousand miles my car started missing above 5300 RPM's. Pulled a few out and they looked like the stock AC delco's that were in their 50 K. Just put headers in and some NGK TR55's and the miss is gone
Bosch plugs REALLY SUCK go with NGK
