You will need to change the cylinder heads and the intake manifold. The carbureted intake manifold will not work on the EFI heads.
Another option is to fabricate a carburetor adaptor for the EFI intake. We have fabricated thisadaptor and the motor it is on runs excellently. I regret to inform you that this product has not yet been released.
