| Post subject: | Angled Head Shaving? |
Found this on an Aussie Mopar site discussing slant six head milling Quote: once we built up a slant and took 200"of the push rod side and nothing off the manifold side(wedge shaped)to put the combustion chambers at a better angle:smoki to the cylinders-went like stink!!
Any thoughts on this? I've heard that detonation control on a higher compression slant is difficult to do, in part because of open chamber design.-Mac [/quote] |

This a very old trick. I haven't seen back-to-back comparisons of HP, but it makes some sense to do it. I have two heads with angle mills - 0.080"/0.180" (intake/plug side) and 0.100"/0.200". They have worked well in street/strip motors for many years. Meril Bruner has used the 0/0.200" mill and he gave me the idea back in 1991. Lou |

When you do this - do you have to also remachine the head bolt holes and flat bosses? I would imagine so, Greg |

Most people do. I did not on mine since I only had a 0.100" offset. No head gasket problems in 10 years and many head swaps, UNTIL this summer. Not sure why it happened and will pull the head to investigate. Not a head bolt issue, though. Lou |

Lou, When you do the .100" / .200" Angle mill, Does that mean that you do .100" off as a regular head cut, then another .100 at the angle after the first cut?Lou Greg |

Couldn't tell ya. I just told them what I wanted and they did it. Lou |
