WARNING re-new 2 ltr cylinderHeads
VolksVair - January 18th, 2012 at 10:25 AM

Hi All, just a heads up on something that just annoyed the shit out of me, I ordered a pair of brand spanking new type4 2 ltr heads, I spotted sharp ridges in all pushrod tube holes and no doubt, would have cut the new pushrod tube seals on installation, I ground these to an acceptable finish, then installed the heads being glad that I didn't miss them before assembly!.
I was then absolutely pissed off when I found that the rocker gear would foul the casting just above the pushrod tube holes!!! so after careful grinding and making sure the pushrod tubes were blocked off so no debris were to go down into this new engine, the rockers were now free, but I thought I would just stick this up in here to warn others to carefully examine new heads and even bolt the rocker shafts, on before installing heads on motors.
These heads were made in Spain by AMC EVerything else looked absolutely fantastic with these heads cheers Frank

Weird i have used many sets of the AMC Heads and never had the problems you mentioned.

So I am the unlucky prick to receive a set of heads that were manufactured on a friday:grind:

here is a copy of a reply on DSK;


I've looked into AMC heads before, I think the general consensus is that the casting are generally good, but have issues like you've found. There are some that recommend getting everthing replaced and then you'll be close. I think Brothers and Darren Gurrola have said that they spend around 10 hours getting them right.

Hi Frank did you also have to clearance the castings so the tappet covers would fit? The AMC heads are great but these little problems cost time and money to fix but they are still a more viable option than the exchange heads.Cheers Les

Hi Les, one edge needed just a bit of a lick as it was a whisker too big, tappet cover fit like a glove on the other head.

What happened to the days where you could buy something new and it would fit & function correctly:crazy: cheers Frank

another reply on DSK, this time from Steve at Kombi Rescue,

Frank the other more alarming issue is that the rocker post location is different to a gen vw head and lash caps should be used on the valve stems to help aid geometery cheers steve


Now I did notice that I had to take up a lot of slack with tappet adjustment and did wonder if it was going to be a concern, I didn't even know lash caps were available, shit, didn't even know what they were:rolleyes: Gene Berg sells them, have a look in ebay
