Changing heads

[damicotile]

I am changing heads to Tims Stage 2's.
My question is, is there a trick to locking down the cylinders while removing the old heads without disturbing the bases?
Resealing those are a pain.

Hi Guido! Good question. If you don't disturb the seal of the bases when you take the heads off, use some tubing (a little bigger than the studs and already cut to length) and the head nuts to keep the cylinders seated. 2 per cylinder will be enough to keep them secure. Of course, if at any time a cylinder comes loose the base will have to be cleaned and sealer reapplied. What did you seal the bases with?

I think he wants to know how to lock the cylinders in place before removing the heads so getting the heads loose won't disturb the cylinder to case seal. This is a crazy idea but if you can tie the cylinders on opposite sides together with rope or strapping?? Run it over the top fins of the cylinders and tighten it down so both sides stay firmly attached to the case. Oooh, cylinder bondage, I'm getting excited!

I don't know why but that's funny to me

No tricks to this one. Just wiggle the heads to unseat it from the cylinders. Normally this doesnt disturb the seal when i do it. If it does, just reapply sealant. Happens to one on rare occasion.

I'm using that Permatex hi-temp black silicon. No leaks but I have had to remove the heads twice, once cuz I ate a carb manifold washer at cam
break-in and once when I thought I had a head leak and both times the barrels came loose. I resealed them but what a pain. I was thinking that if the case was drilled and inserts put in (4) beside the barrel bases, a jig type clamp which would go into the fins and then bolted to those inserts it would lock the barrels in place so the head could be removed for anything from head changes to PR seal replacements without disturbing the seal.
Just a thought.
Resealing without completely removing the barrels suck.

If I did remove the barrel off the piston would the rings have to be replaced or could you just hone the barrels and use the same rings?

Even if you have to remove the barrels you usually don't need to replace the rings or hone the barrels unless you have a fair amount of mileage on the motor or you were burning oil.

I think drilling extra holes in the case should be avoided if possible. My 2 cents.
