Does anyone know if a 287 head, which has had the bolt holes opened up for use on a CB with 11mm head bolts - would still work on a '85 T1 with 10mm bolts? Would a sleeve be required?

It will work just fine. No sleeves required.
WOW!! Now that's what I call a quick response - thankie very kindly!
They sometimes just fit other times I have just ran a 7/16 drill bit through the holes to give enough room for 11mm head bolts on the older heads.

Hehe, I thought the same thing until I re-read it.
Thanks guys...I bought this head to use on a 2.5 CB project for another car, but my brother's 85 1/2 XT developed a 'need'...
In fact, one of Matt's first ported exhaust mannies is still waiting to go on that 2.5, I think that's my nasty core in the 'before' view in your sig!

Just remember, the head bolts don't locate the head to the block, there are 2 dowel pins in the block that locate the head so the head bolt holes can be 3/4 of an inch,
