'68 318 to carbed Magnum 5.2: Check my checklist

When you're referring to the E58s, E55s, and the alternate heads, I take it you're speaking of the pre-'88 carbureted LAs and their variants, correct? Just want to clarify. Far as I know - the roller cam motors, both 318 and 360, used the 4448308 head almost exclusively - as does my '89 360:

Yes. I'm talking about 1978-1980 motors primarily. As far as I know, the last time 360s had something significant optionally is in '83 when the 2bbl option went away and they all got Tquads/Qjets.

So- the "308" head was used by '89-92 360s. They're open chamber, 1.88/1.60, large port, "swirl port" heads with enlarged pushrod tunnels- alternate part #s for them MAY exist. '85-'91 318s had closed chamber, 1.78/1.50, small port, "swirl port" heads with enlarged pushrod tunnels. There's at least one other part # for those, and 302 is usually common to carbed motors which are '85-'89 car and '85-'87 truck engines. The 318's were a weird deal since all the 318s went to roller blocks in '85 but they didn't all get roller cams- 4bbl cop car motors got 360 open chamber heads and flat tappet cams and trucks prior to '88 got the old flat tappet cam though they had the 302s. 360s prior to '89 didn't ever seen to have the roller spider threading.

Maybe no interest in the 318 version of the roller cam engine, but I'm still surprised about the general lack of info on the roller 360's. Magnum 5.9s grow on trees everywhere but in South Florida, apparently.

No, Magnum 5.9s are fairly rare here but the TBIs 360s are probably rarer. Most people like the TBI blocks since they can build a Magnum or pre-Mag motor with equal ease, by that virtue they're an excellent foundation for a build. Here the TBI 360s usually go for more than Magnum 318s and other LA 360s. Talk of early blocks being higher quality and people not going roller squelches much of the interest in the TBI 360s. I find it interesting myself the lack of widely available information on the later '70s/'80s motors as well.
