Looks like the ones I bought with Summit brand. They seem to be working flawless so far

Lets have a discussion about roller lifters. I looked at those, seems like a potential deal for a roller block.

Here is what I want to do. I have a rebuilt 351 Windsor that came out of a truck that I have been gathering part for on the side for a while now. I've got E7 heads off of marketplace, and Edelbrock manifold, finally got me a new oil pan and pick up. Etc. Its a non roller block. I've turned my thoughts to the cam. Good used Ford racing cams and such seem to be all over marketplace. While I was looking at your link, I spotted these:



I looked at the same problem.  After looking around I just went with Comp Cams retro roller and one of their cams.  I do not know if it is a reduced circle or not.  I figured that I would be better off if I purchased both from the same vendor rather than save a few pennies and split the order between two.  A mistake is much less likely. 
BTW: I have ported 351w iron heads Do0E.

OOPS!.  Sorry, Keyed at the wrong place,

Looking for retrofit roller lifters gets confusing. Clearly 5.0 lifters won't work because of the bore length, that is obvious. Where it gets confusing is some lifters are marked as retrofit, but fine print says you need a reduced base circle cam. I know comp cams makes a TRUE retrofit roller lifter, but I cannot find the specs on length. So what are these? Retrofit lifters that fit a stock size roller cam, or retrofit lifters that need the special reduced base circle cam? Really seems like manufacturers need to specify and mark these better. I'm confused, you know the Chinese knock off designers are too.

I'd like to find a reasonably priced set of true retrofit lifters, then a nice used roller cam and then be good to go. Since this is engine #3, its a budget build. Kind of look what I built with everyone's used parts kind of thing.

Just find a 94 or newer block. Probably cheaper than special lifters or cam

There is no such thing as reasonable retrofit lifters.  A quality set is now in the $500 range.  I would never trust my engine to Chinese junk.  There are horror stories about these all over the web.  Best case you get a set that is too loose in the bore and you have super low oil pressure.  Worst case one comes apart, the needles jam up the oil pump, and the whole engine gets turned into junk.  So I must agree with MS on simply finding a later production roller block. 

Or, just put a decent flat tappet cam in the block you have now.  Honestly, a set of E7 heads isn't exactly going to set the world on fire on a 351.  They were marginal heads on a 302.  The 351 is going to make plenty of low speed torque, so the principle reason to use a roller in a low RPM engine goes out the window when you have displacement.
