Not without major work.

They would need to be converted to reverse flow cooling, to match the LT1 block. That involves welding up some of the coolant passages, and drilling holes for others. You would need a manifold other than an LT1/LT4, unless you had yours converted for the revised bolt pattern, and to add the nipples for the Gen 1 coolant lines for the heads.

Then, with 64cc combustion chambers, they would only be good for a blower motor, since the compression ratio would be so low.

so would it be easier just going with afr 227's? and is there any other head that is about the same about of work to do as the afr 227 but more flow after a full port from ai?
thanks
