Hey guys, I've been out of the smblk Mopar engines for quite a few years now, I have a 1970 340 shortblock to build, no heads currently, I'm wondering if there's any aftermarket offerings aluminum or cast that are ready machined bolt on assemblies, or companies that offer built to spec remanufactured factory or aftermarket assemblies, my requirements are they appear externally like factory 340/360 castings, work with factory LA exhaust and intake manifolds and factory 5 bolt valve covers and retain the factory sparkplug angles, not interested in newer Magnum assemblies, I've searched the various vendors with little results and the assorted feedback on various forums about Aeroheads/Indy/Hughes seems iffy...I figured some here on Moparts might have some current purchase/use experience with aftermarket "factory/factory appearing" smblk 340/360 LA heads?

TIA
Mike G
