Limited and open flat heads

So today went down to my friend Craig's to use his lathe . He was just finishing putting together a limited mod flat head . Had got the open done before i got there .
The limited had a precision cam with like 458 lift and 306 duration , big ass cam .
The open has 125 over piston and a lunati stroker crank and all the goodies .
Here some pics of the motors and him milling the head for the open , also cutting valve reliefs .
The open is the one with the head studs.
