Well I know what I would do and thats shorten the stud by the corresponding amount that the block has been decked. It wont effect the strength as you will still have the same amount of thread contact, all your doing is moving the stud down so the collar is flat with the block face.
Either take them to a machine shop or use a bench grinder to whittle the end down. Don't try and hack saw them. Looks like you only need 1/2 to 1mm.

A good tip is to screw a nut on before you grind so when you unscrew the nut afterwards it automatically cleans the threads

Thought it was the collors not the stud length that was the problem as the recess they sit in will be smaller if it's been decked. Needs that recess made deeper by looks of it

[grcossie]

Will say the same, you have to get a machine shop to re drill the recess, to get the collors sit lower in block

damn thats not good now its all built....what if i was to turn a mm from the bottom of the collar on a lathe wouldnt have thought it would weaken them ??

[grcossie]

Maybe you can do that, not sure. Maybe jimbo now??

[cozzylee]

was hoping jimbo will be along as im sure he will have the answer few ways to go about it just not sure witch would be the best

[Cossie col]

Would have thought it would be less than a mm or your going to need the pistons done aswell

[grcossie]

Yes it is, the best way is maybe not the cheapest, but safest as it usualy is

[cozzylee]

yeah its less than a mm im using a 4 layer mountune gasket aswell so thats around 1.6mm

It depends what pistons, rods and crank ho is used. Of course he have to check how high the pistons are going

What comp do you have??

[cozzylee]

7:6:1 think it should be ok

[cossiedavid]

the holes need to go deeper or you could take a bit off the top of the coller save taking the pistons and crank out

Sorry I misunderstood , I thought the studs were too long not letting the collar go flush
