My '73 2.0 motor needs a rebuild. Different shops are recommending different approaches to replacing the heads, which are both cracked (near the spark plug holes).
One shop doesn't believe in using "Chinese crap" and wants to try and search the planet for NOS or great condition heads, but has no leads (nor do they think welding/repairing my heads is a good idea). The other shop is open to using high quality repos like the Len Hoffman 2.0 heads. What have folks used for replacement heads on a 2.0 rebuild that are performing well years later? Are there any options out there for finding NOS or top shape used 2.0 heads? FYI - keeping the motor stock - no mods on the rebuild. Thanks in advance. |

European Motorworks (Jorge) in Hawthorn repaired my 2.0 heads a few years ago. Plugged the spark plug hole and re-drilled to 12mm. Don't know what they currently look like as I haven't dismantled the engine but was running nice after about 30k miles. Restoring the car at the moment. Might reopen the engine later.
Good luck! Seems like you have a few options between those NOS one offered, the AA new castings, repairing the current ones, and more. Something to remember, the 914 2.0 heads were re-engineered by Porsche, that is why they differ from the bus 2.0 heads. They offer better performance. HAM (well known in the industry) does use the 914 2.0 chamber design in their heads, so it must be a good one. (IMG:style_emoticons/default/smile.gif) |
