the ls6/ls2 243 casting heads flow the best of the factory castings for a small bore.

Yup everyone wants the LS6 243 castings, I see them sell for 250 -500 in stock form, and nice shape all the time.

Yep, and I believe it can be worth 15-20rwhp stock.

Great head for a budget build, because not only are you getting more flow; you are getting a bump in compression as well while keeping stock PTV clearances.

And keep in mind should you get more $$$ down the road, you can send them out to be ported later!!!
