452 Head question

I figured it would be something like that. My block is stamped HP but no windage tray. It's wild how so many of these "same" heads come with many minor differences. For instance, the heads that came with my block have the big chunk behind the guide boss in the pocket, the 452 head you sent me does not, actually makes it much less work for me grinding it out, so good deal. Thanks for the quick shipping by the way Punk.
