Aircooled VW South Africa

A couple of pics of a job I am busy with, I am hoping to finish the job tomorrow.....
Pics are only of the one head, which isnt complete yet

Heads as I received them


After having the heads cut for higher compression


Full chamber reshaping with old valves in place.
Head also checked for correct volume - 44cc on left, 44.5cc on right - close enough


more to follow as the job progresses

Whooo-hoooo! looking nice Tony

Heads are done and ready to be shipped back to their excited owner...

Decided to do a little swirl polishing.....
before


after



polished the valve heads to reflect a little heat
before and after


final product





The pictures of the ports didnt come out at all and the box is now sealed.
Inlets and exhaust ports were worked for better and straighter flow
Manifolds were also match ported to the heads.

I like it, Yaeh

hi tony are those stock vw tp heads?do you have any links on porting stock heads want to try on my 1717cc its running good with the new carb but its ports are stock and rough would love just to clean them up but dont want to f them up...

when I received them they were bone stock 30yo twin port heads

If you have a single carb you will get nothing out of porting the heads.

Centre mount 38 dncl weber downdraught...the carb does make a big differance got the stock 34 pict back on as my dad is using the motor in his daily driver at moment bacause it was heavy on juice but with the stock carb it doesnt sound like it has worked cam in but with the big carb you can cleary hear the cam and it revs like a bike...but im sure with some head work i might pull some more ponnies or what?

possibly, but my experience with center mount carbs is that you will get more out if you do something about the manifold - they are usually pretty crap and restricted inside.

i built the manifold out of exhaust tubing so it should only have some restriction where i welded the flange for the carb on...but like do you have any links to basic vw head porting or books?or does how to hotrod you vw show basic head porting?i built the manifold out of exhaust tubing so it should only have some restriction where i welded the flange for the carb on...but like do you have any links to basic vw head porting or books?or does how to hotrod you vw show basic head porting?

There is a good head porting article at http://www.callook.com/basic-head-porting/
