Head Porting Questions

[Yellermanx]

I have acquired an extra set of heads for my basically stock dual IDF carb and extractor exhaust 1600. I want to try my hand at a little porting, nothing wild just trying to make them a little better without hurting them while at the same time learning a little something. I have read the article on CLF and have the "How to Hot Rod Volkswagen Engines" By Bill Fisher. However, the pictures in both of these are a little vague. I have seen better pictures somewhere but can't find them now. My two major questions as of now are.

1. Which gaskets to use for intake template?
2. Where can I find better pictures?

I plan a bigger engine some day, but want to try this for my own satisfaction.

Thanks in advance

Cal-look.com has an Tech artical with pics.

unless you understand norwegian the text in this article will be worthless to you.... and the pictures arent that good either, but anyway it's better than nothing.

In the books "Aircooled vw engine interchange manual" and "Vw beetle performance handbook" there's some good pictures.

Here's a picture of an unfinished porting job on a set og 042 mofoco heads, with 40x35.5 mm valves. (this is done by me, and i'm no expert, so any comments by people who know what their doing would be good)

I did the Cal-look.com. I took them to a long time VW machine shop and he said I did a nice job. It will take you a while, about 10 hours with a Dremel.

Remember, if you do the Chamber, where incidently you get most of your gain from, you will have to have them fly cut to regain you compression.

If those heads have a hump in the Intake port, do not remove any of this! It is the supporting material under the Valve Springs.

ultra VW did a good article on porting stock heads, but I can't remember which one. www.ultravw.com

for a stocker, use the metal intake gasket as a template.

I wrote the article on Cal-look.com. I have all of the original pictures I can mail you if you like. When they imported them on the the server, some clairity was lost. I'd be glad to send you whichever ones you need in thier original format (much clearer).

Thanks Tom I have read your article several times. I just want to make sure I understand everything before I start. I PMd you with my e-mail address and would appreciate the pictures. Thanks. Thanks to everyone else for the replys, I hope to start this project soon. I probably wont be able to tell for sure if the porting helps since the new heads already have bigger valves than the ones I am replacing. Keep the replys coming.

Thanks, Chuck

yeller/Chuck, what do you have for tools to port them? I never used a "traditional" hobbyist Dremel since most are made for low-power use (under 2-amps) like for model cars, etc. I feel those are far too weak for grinding aluminum and would therefore take "10 hours". For years I used a carbide cutting bit in a variable-speed electric drill with satisfactory results. This year I stepped up to a hi-po Dremel (about 4.5amps, on sale at home supply store for about $70) which really lets the chips fly (therefore always use face shield or safety goggles) in comparision to the drill. Clean out the bit with either a small wire brush or dipping the bit in a toilet sealing wax ring . That Dremel would be "closer" to a pneumatic die grinder that I imagine most of the pro's use, but for the pneumatic die grinder you need a hefty air compressor.
