I'm just sitting here bored right now and would like to let you guys in on the project my Dad and I are doing right now. Just some minor port matching and polishing. So far we've polished the combustion chambers and piston tops. I've port matched the exhaust and intake sides of the head and my Dad and I are currently polishing the exhaust ports. Here are some pictures of the progress. Sorry about the quality they were taken on our less than 1mp digital camera.

looks pretty kewl.

 

Looks good. What are you using to do this?

 

Just a couple dremel tools and lots of emery paper.

 

use 220 grit sandpaper when all finished , a little roughness will aid in better atomization...

you could thin the dividing wall a little more also , hopefully you didnt go into the roof of the ports , it appears as though you just attacked what was easy to get to , which is where most people go wrong , you want the increase the radius and allow air to flow to the valves as easily as possible , not just take material out where you can.

that will make for very slow moving turbulent air.

You seem to have misread. The pictures are only of the exhaust ports and I haven't really "ported" the engine. Just portmatched it to the gaskets so the air would theoretically flow as directly as possible in and out of the engine. The intake ports haven't really been touched other than being portmatched to the intake manifold gasket. I haven't actually done any real porting because I dont have the tools..eg flow bench machine or experience yet.

 

I think it looks pretty good, even with the crappy camera. As long as you didnt take too much out and just smoothed out the rough stuff from the factory, there shouldnt be a problem.

 

yeah looks good what tools exactly did you use turn this post into an how to i would love some more info on this.

 

Alright. Once I get some more time and some more pics I'll try to give a more in depth explanation of what my Dad and I did. But I'll tell you one thing. It takes a lot of elbow grease and a couple of layers of skin on your thumbs. This is one of the reasons why my car isn't up and running still after a longass time.

 

use a grinder and a compressor both are cheap, and it looks like ur here in san jose bring the head by sometime id like to see it in person.

chris.

 

more pics please.

flow benches arent really required , neither is experience.

all you really need is a basic knowledge of airflow charateristics to analyze what needs to stay and what needs to be removed/reworked.

 

Heres some more pics if you guys care.
