Home porting pics

Well, I finally finished 1/4 of the head. I've got all the rough cutting done on the other three but I still need to smooth them out. They're far from perfect but a huge improvement over stock. The second pictures make things look rusty, but they're not, just a really crappy camera that no manual manual setting to get good pictures with.

Here is the one that is finished:




Here's a bad picture of the intake port:



And another bad picture of the exhaust port. It is a full 1/4" bigger diameter than stock!



What do you think?

A good start but a bit conservative.

What year head is that? ('89-'94 or '95+) By the combustion chamber I'm guessing the older of the two.

It's a 91. Please explain "conservative". What else should I be doing?
