Who does quality sleeve pinning?

I've decided resleeving is a bit much for my street application (15psi or so), but I'd like a little extra protection. Any recommendations?

anybody with a drill and die and tap set, even a carpenter could do it, they shim doors all day.

Is there a URL that outlines how it should be done?

Maybe if it's not too complicated I'll give it a try.

sorry, i was kidding, do not do it yourself - the problem is that there is debate whether pinning comprimises the structural integrity of the block and sleeves as it weakens the outside of the block from holes and the block is top cast aluminum which could casue ot to separate laterally from casting direction. also the pins/ threaded rod used to secure the sleeves may exert to much pressure on small areas of the sleeves when the motor gets hot and toques naturally with the head.
I have tried to simply o-ring the thin sleeves that are in there with copper head gasket, this way they actually stay in place by using the head gasket and o-ring.

Most machine shops can do the work for you, should not cost more than 150 if you bring then the block with head separated.

That's actually something like what I was thinking of. Use some sort of brace around the sleeves themselves that just barely touch the sleeves, and then run the pins into that brace. That way there is no modification to the sleeves themselves, just the block. Think that would work?

what I tried to describe was actually scoring a groove on the top of the sleeves, the acual gasket mating surface not the sides.
with no work at all you can install a Nuformz blockguard, they work quite well for the money invested abt. USD 120.
When you are ready for big power there is no debate about resleeving...right

This might be more than you're interested in, but you could have your block close-decked as well, seal the waterjacket and tops of the sleeves.

Only thing is I've heard that blockgaurds hinder cooling and don't support the lower portion of the sleeves?

Maybe I'll just bite the bullet and have it sleeved. At least that way I can bore it out a bit.

AshlandSi

Any repercussions to this?

It seems to me this is another hindrance to cooling, plus still no support for the lower portion. The thing about the pins that I like is that it doesn't affect cooling and you could also pin the lower section (I'm guessing, as I've never actually done it before, but don't see why you couldn't).

no cooling problems at all, look at the head which has the water passages in it, only they need to be filled the closed deck will have the holes lined up with those in the head. this is the way to go closed deck either with darton, golden eagle sleeves, I thought you were on a budget.

I am, that's why I'm trying to find an alternative to sleeving which seems spendy ($800 or so?)
