This thread has made me nervous
http://www.914world.com/bbs2/index.php?act=...=ST&f=2&t=33950 I have my engine ready to pull in the morning to do top end rebuild and after reading this thread about lapping the cyl to the heads I am getting worried. I am having my heads re-built and buying new P&C's. What is the proper method when bolting the heads back on? Use seals or lap them. I have no idea how to lap somthing properly except my wife (IMG:http://www.914world.com/bbs2/html/emoticons/grouphug.gif) so what do I do? I watched Jake's type IV teardown and assembly and he made mention of not using the seals because of the buliten but didn't say anything about lapping either. I am tempted to take my pulled engine down to my local VW shop and having them do all the work because I am scared LOL Luke D |

Has anyone, besides me, done a close inspection (magnafied inspection) of heads after they have been flycut? It's, a cheap fast way to cut heads, and in all reality, it's not a quality job, and it's not the machinist, it's the flycutter, it's not a precision tool. Thats why I perfer copper head gaskets, not only do they help seal cast iron and aluminum, there great for setting up compression ratios. I, set up a motor 1 time, and the piston stuck out of the cyl .020, and with copper gaskets I got the CR I needed. (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) CNC end mill, would be a nice quality way to cut heads, I can't aford that, so I use gaskets So, lapping the cylinders, would be a benefit, if your not useing head gaskets. This is my opinion, and others my disagree, even though there wrong.
