What would you gain?? It would still be a pushrod non-crossflow singlecam leaning-over piece of crap...

 

You'd be better to try and fit a newer head onto a 4K block, but seeing as they are all belt-driven twincams it is not easy.

If 5k is too hard, I got good results from a 4k with 32/36 downdrafft weber (off a wrecked alfa) mounted on adapter plate to standard manifold and extractors/exhaust. The head was planed to bump compression and I fitted an electronic dizzy out of a hiace. Cost around $600 including exhaust done at mate's rates. It did rev well but at the end of the day it was still a 4k.

 

Any more mods than that you're better off with a 5k as they are a bit more torquey.

 

Now have 4age and wouldn't go back to k series. (sorry k series fans)
