As the title says, is this head usable? I have several heads however each set has one unique problem, I am trying to find out which I should use.
My question is regarding the large dimples in the chamber- I am not talking about cracks or other issues. (the guy that I purchased this from must have really pissed his neighbor off. He said his neighbor put a nut in the spark plug hole. In addition, F#$@ You written on the head with a sharpie) Attached image(s) |

for a door stop!
only if you had to. it looks pretty bet up, you'd have to get it checked for cracks [some say they are all cracked]. and check to make sure the valves are not bent. |

Not worth it, IMHO.

I would be most concerned about cracks and the condition of the valve seats, guides and valves. There also must be enough material so fly cutting will clean up mating surfaces. |

Not sure if there is a crack, it is too damaged for me to tell. This is the worst of the 6 heads that I have to choose from. I was just curious. I have another head that is in decent shape however it has some mild pitting. How deep can they go when flycutting without causing issues? |

Steve, you could salvage those heads if you learned to weld aluminum and didnt mind wasting a lot of time getting them correct. I think we are alike in that this proposal sounds intriguing rather than a huge waste (IMG:style_emoticons/default/smile.gif)
For finding cracks, you can use the same method that some texts recommend for finding scabie burrows (IMG:style_emoticons/default/wink.gif) (inside Dr. thing). |

Find not treat. Use toner ink, or other powdered ink/dust media to find cracks (IMG:style_emoticons/default/wink.gif)

That head has been flycut a lot. The compression ratio on those two cylinders will be elelvated.
Someone polished the chambers and my guess is they were used in a Hi-Perf application and obviously something went wrong. My advice? Step away from the junk head! |
