Head Porting Finally Finished
Here are the last few pics of my DIY head porting. I got them about 90% of what I was aiming for. Maybe next year I will have them Extrude Honed to get that last 10%
The hardest part is getting around the guides to get everything completely smooth. I know for a fact as many imperfections and bumps these will flow way better than stockers. The bores are all straight and everything is ready to go back together with the new Race Tech lightened valves and Riva valvetrain.
I may put the head on the back burner till the weekend and thermal coat the valve faces and moly coat the stems if I have the material left????
Total cost was around $100 and probably 12-14 hours of labor. Not bad if you have the patience and time to do it.

Hey guys I wanted to bring this thread back up and gauge any intrest from anyone to get their heads done over the winter.
The pictures in the thread show how well the final job came out.
There are a lot of places in the stock head that have really bad flaws that hinder flow. I will clean up around the guides as in my pictures but will not remove any material from the guide itself as I feel that the guides need to be as long as possible.
What I am going to try to do is to turn a head around in 7-10 days.
Cost will be $650 plus return freight for a full port job. Another option is that I can coat your valve stems and springs with a Moly Dry Film coating and the faces with a thermal barrier coating. You can read about these coatings here: http://www.techlinecoatings.com/Engine.htm
Cost $150 for a full set of valves and springs
If you are looking at getting new valves feel free to have Jerry ship them to me and I can assemble your head with the new valves and ship it complete to you.
If anyone is interested shoot me a PM.

Did you see any gains from that nice port work you did??? You first posted may 14th so I would assume you have tested by now.

To tell you the truth I was down all last year, don't ask
Jerry don't poke fun
I did do a head for a guy in Florida a while back and he said that there was very noticeable improvement in bottom end and acceleration.
He could not swear to any top end but all in all he was very happy.
He was running a basic stage II but could not swear what parts were there as he did not do his own wrenching, but did see the improvements with only the head porting and no other changes.
Maybe some of the guys with ported heads and stock size valves could chime in?
