Cleveland And The Lsx

[Titan7]

My buddy just finished building a cleveland. And I currently in the middle of my ls2 build. All I'm missing is my heads and cam. He has a set of 4v cleveland heads that he said he would give me for a case of beer.
Now I've been reading that LS1 heads will fit on a cleveland block. But will cleveland 4v heads fit on an LS block??
I know I'll have to have a custom cam since LS is ei/ei/ei/ei and the cleveland is ie/ie/ie/ie.. If this cleveland head on lsx block combo is possible what else would I have to have custom made?

You would be way ahead in both power and money to put L92 heads on it. They will outflow the 40 year old stuff by a lot. Especially at low to mid lift. They are also very light.

L92 will flow somewhere in the 325-330 range at .600 lift.. I've heard of cleveland heads flowing just as close. Yes maybe a little less and probably heavier. Which is nothing nitrous cant take care of lol. But canted valves. YES PLEASE!! Reving to 8500 should be a dream come true and easily done if this setup is even remotely possible..
I'm searching for knowledge to see if anyone would know if I needed anything more than a custom cam and a LS2 truck intake?

You think an LS2 intake will bolt up to cleveland heads?

I would t see why it wouldnt fit with a little port work.. The LSx motors were mocked from the cleveland motor. Everything I have seen is basically exactly the same minus the valve order, canted valves on the cleveland heads, and the swap of the 8 and 3 cylinder firing order.
