Frankestein Engines

I know that there are frankenstiens for the B series, but are there frankensteins for the K or H series? Just a thought for future reference. If there are can someone give me the build ups or sites for them. :sunglasse

for the H, you can put the H23 block w/ the H22 head.
for the K, i believe you can put the K24 block w/ the K20 head.
