well mine are cracked [img]i/expressions/face-icon-small-sad.gif[/img], and i can't find the part # for it and neither can the dealer, does any know what it is?

 

woods sells replacements. they need to be bored to allow proper valve stem clearance once pressed in.

I assume you're talking about the intakes - you could just file the OEM guides that are cracked, flush with the head.
