Default Need part number/source for bigblock dowels

I'm building a new engine, and I need the dowels on the block decks that locate the heads, and also the dowels that locate the bellhousing. Anybody know the numbers and some sources for these?

Thanks,
Mike

Summit racing has them. Your local machine shop should have them as well.

They can be difficult to remove. You may have already taken them out with vise-grips...dunno. Most machine shops use some variation of the tool below since the dowel is usually re-used after decking and using vise grips does a job on them.

Here's the tool I mentioned.

Okay, gotcha now. The block is new, and the cheap sob's at Chevrolet don't include these parts. Would have been nice if they could have just thrown these things in a bag for the customer's convenience.

Thanks for your help, guys!

Strike up a friendship with a starving local auto machine shop. You'll be glad you did

Tool I have used for dowel removal when I didn't have access to a proper dowel puller is pretty exotic, they are called Vise-Grips

Check Scoggins Dickey. I think they have a kit with everything included.
