Hi all...
I have a 73 2.0 liter that has been converted to carbs. I'm using a phenolic spacer under the intake manifolds to stop heat from cooking the carbs. Problem is that the studs that attach the intake to the heads are now too short and the nut only holds by a thread or 2. Does any know what I can use for a longer stud? Or maybe someone knows the specs of the stud? Is this a good idea? Will the old studs come out of the head? Thanks, Mike |

8 x 1.25, I think 40mm long Yes they can be removed using the double nut trick. Most auto shops will have longer ones or you can order them from Amazon |

Are you using tall or short intakes? The Belleville/schnor (sp) washers, used on cv bolts, are a good option if you are using cut steel lockwashers. The B/S ones buy you a little room and you don't need a bunch of torque to get them to work.

I wouldnt add the spacers, especially where you live. You want the manifold to heat up quickly in colder climates. Just install the thick paper gaskets. You won't harm anything

Thanks, Mike Same problem on mine... a couple of the nuts don't reach the nylock as the previous owner set it up. Two mechanics looked and weren't too concerned about it.... but kinda bugs me. |

CB tall manifolds have thinner bases than the 'shorties' I've come across.

You won't harm anything When I bought the car there were no spacers. After shutdown the carbs got so hot that the fuel would boil. Added the spacers and problem solved. |

around 1/4". that's buying you some room and might allow retaining the phenolics. what are you using for washers?

You need a thin washer. 8mm that will fit under the nut. PVT nuts are good if you're scared of vibration but I've never had an issue with a nylon lock nut. I use these on velocity stacks for extra "grip". https://www.belmetric.com/stainless-high-type-c-3_752_1481/ |

That thin washer is the one for the cv bolts. Standard metric nut.
