Looking at the flow numbers on edelbrock's website shows the two being virtually identical. Is there something I am missing about the magnum heads? In Edelbrock form is there really any performance difference; or is the reason people go with magnum heads because they are generally going from a set of poor flowing smog type heads on a typical LA engine.

If you have a magnum engine..try putting the LA version on it...how you going to get oil into the shafts..??... yeah...some early magnum blocks might of/ could of came with oil hole in the head...but is the cam drilled to feed the oil galleries...or you can take it to the machine shop and have the oil passaged drilled...good luck on what that will cost...

Then T off of the oil port at the top rear of the block to feed em & a holley jet in the passage to meter the flow. live every 24 hour block of time like it's your last day on earth

I did it on my circle burner for a different reason (eliminating some of the leaks at the cam bearings) live every 24 hour block of time like it's your last day on earth

Different things need doing, but in terms of labor and cost, not really much different. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
