roller cams for la 360 /questions

I put Morel 5123's in my 273 that's going in my 65 Barracuda. I have not fired it up yet, but it is going to the dyno late next week. The only issue that I can think of for a later LA roller block is, they may or may not be able to be installed/removed with the heads on. The LA roller blocks supposedly have taller lifter bores than the older LA blocks. I can get my lifters in and out with the heads on, even with having had the lifter bores bushed. The tops of the bushings are very slightly above the tops of the old bores, but I can still get the pairs of lifters in and out with the heads on if I hold my mouth just right and keep my temper in check....lol. All you can do is try it and see.
