true... you just have to block off one of the coolant passages since LT1's have reverse cooling. If you bolt it on, it will dump coolant righ into the oil valey and then you got problems.
also, there are some bolt holes that need to be moddified i belive... not 100%

i was under the probable false impression that it did not have the coolant ports in the right location, so in order to make them work youd have to somehow impossibly drill out the port holes in the correct location.....but then again, you can make lt1 manifolds work, so maybe lt1 heads CAN work.
anyone else have any theories?? this might be a good topic to start.
anyone done this?

It has been done...but I agree to bolt on the Vortecs...much better deal...bolt on and go for the same approx. power potential.

Yes, it can be done. Search the web. I found a page with photos, specific instructions, and details. I just can't find the link I thought I had bookmarked.
Plugs need to be welded into and machined flat on the deck side of the head in a couple of coolant passages. A steam line needs to be installed at the rear of the heads. Beyond that, the swap was fairly straightforward.

IIRC, tpi_roc has done this already, even had pic's showing what he did.
Seemed like a lotta work/expense..but to each his own.

yeah it sounds like its just too much work to modify them, a good set of aftermarket aluminum heads woud be alot easier to setup, but more expensive to buy.
