Anyone have a good recommendation for a guide to head porting. I know what the jist of headporting entails, but would like the finer point for reference. I have looked online for a good while and cant quite find what I am looking for. I do alot of metal work, but have never done heads before. I just picked up a couple of sets of stock LS1 heads and I am going to give a wack at doing it myself. Any info would greatly be appreciated.

Thanks

Brandon

I don't know of one. I've read several good magazine articles through the years that were correct and informative, but those were few.

Best thing you can do is find a reputable head porter in your area and pay him to tutor you.

Well while good in theory, thats hard to workout in real life. I actually studied with a machinist for a while when I got out of high school, but do to my work schedule this would be difficult. Although it would be well worth cash for someone that knows what they are doing if they would like to do some teaching on the weekend.

Any Takers?

I agree with Greg. All a book is going to do is describe and show you what the port is supposed to look like, YOU can do that without spending 20 bucks. I will say that David Vizard has some great information in his books, more noteably his SBC cylinder head book, on tricks of the trade. The main thing is not doing the intake or exhaust port but doing all of them to match each other. Get you some card board and use as a template for measuring and cut to fit the first ports you do so you can visually see how to shape the others. One thing I will say since I have done a couple is some pairs of heads do not match, you will see that one head has very slightly larger ports in it than the other one so that may make it harder for you to match one head to the other. TAKE YOUR TIME, the more time you take shapeing and blending, the better they will turn out. 260-270 is real easy to get if you do that. Do not hog them out, the port is already 198-202cc's in size, just shape and blend. Also on the exhaust side there is a coolant passage above the port were that small "bump" is, so when you port match the port to your header start about a half inch in so you will not hit it. Good luck.

Can't point to any book, except perhaps Vizard's book (Vizard is a good author though). But, you might consider Joe Mondello's courses.

Great information.

I would LOVE to take a course like that. However, there is no way that I could take my vacation time + $3000 to go do that, plus the airfair. It would be sweet though. Surely there is a local guru that would like to get some semi organized classroom stuff together. That would be a good way for someone to net some pretty good cash. To teach 2-5 people at a time on different points of engine building/machine work. Dont you guys think?

If anyone could think of a Dallas area local guy that might be interested, I would be willing to do all the recruiting and organizing. They would just need to bring the knowledge.

I guess my idea isnt as kean as I thought.

Greg Good

Get a hold of Trevor Johnson. He's in your area, and he's a damn good head porter.

Us head porters all know what we are (******), it's just a matter of price.

Make it worth his while and he'll probably do it.

Hysteria

Well said. Head porters do it for either the love of doing it or for the money because they are good at it, some do it for both. Either way you will be able to talk him or someone else into helping you.

Well I am a self proclaimed *****.......... So I can appreciate that. I dont want the knowledge to go start a shop or anything. Just want to be able to do it for myself, and know better about the work. So do you guys have any contact info for the above referenced guy?

There's a couple shops in the area that may know some people. There is FastTech which is a little south of Dallas, and then you have Arlington MotorSports(obviously in Arlington). Keith @ AMS is a pretty good guy to talk to, he might be able to help you out/know someone who can. The guys @ FastTech are great to talk to as well.

i just bought david vizard's book"how to build & modify chevrolet small block V-8 cylinder heads".yes,it's been around for about 13 yrs but there is some very good information in it that can be applied to any head,not just an ls1.it only cost around 15.00.you can buy it at amazon.com.it's money well spent,IMO, if you are going to attempt to port your own heads.

Standard Abrasive makes porting supplies. They have a good DIY porting page.
