I hate to start another thread but.. Went to put the heads on and found only 1 alignment dowl in the block. I thought that can't be right there where none stuck in the heads, so there where 3 missing already, went down to the parts store and none of the felpro sets say they will fit, and it doesn't say the size of them so I can't just buy one that is close. Anybody have any sort of part number for them. Now I have to wait longer to do my heads and it's already been a month since I pulled them.
