I'm sorry, I should have informed you guys.
Everything is stock, the LS has 200K and I
was wondering if it was worth trying to build
it up. And if it was worth building up, I was
wondering what head would be the most
beneficial on this 90 LS block. And also with
what setup, as far as pistons, rods, so on and
so on... . work well with whichever head.
I hope this helps.
