What's the difference between the 241 and the 243? Are they both from 01-02?

241 was the laster investment case LS1 head. 243 was the LS6 head originally, but now is also the LS2 head without the lightweight valves.

I got the 053 # off of patriot performance web site. I guess it must not be a true LS6 head then.

i just swapped my crappy 98' heads for some stock 243's. should be nice jump hopefully haven't got a chance to tune it yet. (i know , why not port them. it's not in the budget. plus i just hated knowing that all of the later model LS1's had a leg up on me)
