Default Trashed Ls1 block!!

FTW! I trashed my ls1 block! A valve broke and dropped into cylinder 2. So I need to know what block to use with my Patriot Stg 2 59cc 2.055/1.57 and trex cam. Should I use an iron 402 Ls1, a ls2 aluminum 402, an ls1 383 or an ls1 iron 408? Which would be the best with my current H/C. What about the interchangeable parts with the Ls2? Thanks for the feedback and opinions!

Are the single springs breaking? Why are these valves falling?

says here valve broke. I would hope he wouldn't be running a TRex with single springs anyway.

402 if you can afford it, 408 if you want to spend a little less money. If I could do it again I would have definetly go with a 402, or maybe even a 414 (L92 block) if you have the money.
