 deck height I measured deck height tonight and got .055 (In inches)  I measure a stock sc engine I have also and that measured .075(in inchs)  just go through what i am dealing with is a the following 98mm JE pistons Low compression turbo application(8.0-1) 3.0 sc bottom end with no offset on the rods 92 cc twin plug sc heads What are you guys shooting for for deck height ?? Thanks so much for your time |

 Time to CC the set up and adjust the deck height for the target CR.  It is fun........... http://forums.pelicanparts.com/uploa...1167371104.jpg Cheers |

 92cc heads I posted that info already;) | 
| 
 I shoot for no more than .040" (.1mm) per Steve Wiener's recommendation of .035-.040". I've measured higher on a stock 964 motor but your SC measurements seem kinda high. Have you decked the case spigots yet? -Chris |

 You still don't know what the CR wil be if all you have is the head volume. You might want to measure the piston dome voume as well.  Cheers |

 henry had spec'd these out as 8-1 CR with stock sc heads(The Je pistons almost are flat with very little dome and valve releifs cut in them already) which is pretty much what I have nothing was machined on the heads other then chamfering and the twin plugging I should restate I measured the 78 sc engine my garage(stock motor) and that measured considerably higher then mine.. |

 If you have the case apart you can have a local machinist "clean up" the spigot sealing surface. This will give you a nice "true" foundation for the cylinder+head+cam carrier stack and get you a better deck height as a bonus. How are you measuring your deck height? -Chris |

 dial cailper in 3 spots 120 degrees apart. Case is together now. I have read a bunch on this and allot of folks are suggesting that 1.2-1.3 mm is good to go for a turbo engine what do you think? |

 I will try the solder method.. I am not real concerned with valves hitting more so to control detonation Thanks guys oh and last question is why would that stock sc have higher deck height then what I have hear?? |
