318 head porting for the average joe

Today i decided to do 'just the guide'. I shortened it's length where it starts to about a 1/2', then slimed it and pointed it to the port window, meanwhile the only other porting done was just smoothing the casting and angles just off the seat half way up the bowls roof s mentioned above ..'still as cast/stock short turn'.

Now here are the new numbers.
