Stop in for a cup of coffee

yeah, i mean someone else might know a work around, but I'm 99% sure you have to either have the heads re-drilled at the LA intake angle or use an intake for the Magnum bolt angles. I know we fought with that for a while before figuring that out. Course, that was 20 years ago.
WHy go through all the work just for a set of heads. There's tons of good usable LA heads around.
