If I remembered an exact number, I would have posted. I may have come across a claim as high as 240, but Id sooner believe its in the low 230s. Might be more depending on the casting, although IIRC all 241's are SPM cast.

Just for kicks, here is a link to some stock 243 heads we flow tested.

https://ls1tech.com/forums/generation-iii-internal-engine/434815-what-do-cast-ls6-heads-flow.html

Both this and the stock 241 flow numbers are from our Superflow 1020 bench, using a 3.905" bore, and a clay radius inlet.
