Default Anyone have lifter bore specs?

My fsm is on the home computer. Trying to get my engine builder moving. Can someone check out lifter bore diameter specs in their manual, if it's there, '99/'00, BP4W head?

If I end up getting it before someone replies, I'll put the specs here and lock the thread.

Thanks in advance, brohams.

Update, I didn't find any lifter bore dia/tolerance info in the 93 or 99 fsm, nor in the Haynes NA manual. One of the fsm's just stated to ensure the lifter traveled in the bore without sticking.

I forgot to check my Williams disc last night, but I don't remember seeing a spec either.

Will look this afternoon.

Want me to measure mine? It's a 1.6L in pristine condition, at least something to compare to. Head's disassembled on workbench.

If you don't mind and remember to check the disc, report back. Don't bother measuring the 1.6, he also has my 1.8 hydro head that he can measure, and it's just about perfect, as well. Thanks.

Ok...my Mitchell (not Williams) repair disc gave me this for the lifter bore spec on the '99:

1.1811-1.1821 (30.000-30.025)
