I have a NOS Magnum bare block with dealer stickers still on it. Someday I want to build it and, while years away, I routinely think about the direction the build should go. The cylinder head choice is something that internally debate. Edelbrock Magnum's or Edelbrock or TF LA? I think I'm going to stay true to my original motivations and take advantage of the tall, un-chamfered, lifter bores for a streetable hyd roller lifter but build it like an LA (heads, w/p, and intake).
