Small Block Top End Performance

In the gallery under David Athans on page 5, I have new pictures of the AFR185 Aluminum Heads that just came in. Going to bolt these on in the next few weeks and will change the cam at the same time.

I am hoping that someone can help me with some information about my 1968 289 block. In the valley at the top of the block, under the intake manifold, I was wondering if there are two threaded bosses in the middle at approx quarter point spacing? I was told by the mechanic who will install the heads/cam that in order to use hydraulic/roller lifters a "spider" mechanism needs to hold them in place and will be held in place by screwing into those bosses, but he doesnt know if my block has these. If someone can help me out it would be greatly appreciated so that i dont order cam/lifters that wont work with what I've got. Thanks
