yes, more 360 questions...

The heads drilled for an LA Intake should accept ANY LA intake. I dont know exactly about what kind of intake the STR12 is, if it is MAGNUM based then no it will not work on LA heads, but if you have it Dual Drilled it will accept ANY Magnum or LA intake.

The STR-12 is a "LA" small block cross ram you often see it's bigger brother on HEMI engines and to a lesser extent, the 440's. The intake has a flat top with twin carbs on each side of the intake top. Not inline. One sits kind of, like over the drivers side valve cover, almost, slightly foward and the other carb sits the sme way only slightly back further towards the firewall more.

OH Wait, WTF is wrong with me!?!?! Here, have a picture. I stole this from "Panic" I hope my fellow Islander doesn't mind so much. If your interested in some serious tech stuff, click this; http://victorylibrary.com/mopar/mopar-tech.htm
