cast iron heads vs aluminum for stroked 340

Heads: If its cost prohibitive to re-work existing heads I'll certainly purchase something different. That's just easy and prudent. I have a hard time believing that's the case though, and I read countless stories of Eddy's that need work out of the box anyway.

Cost prohibitive is only defined by you and your opinion - cuz you'r epaying the bill...lol. Personally it's a lot cheaper to whittle away aluminum than iron, plus a more modern chmber choice that will be required for the power level you want at the rpms you want, plus the lighter weight. If the reason iron is what you want is braging rights - that's the only reason to keep using them in this application when all the returns on investment are tallied. No heads you buy will be ready to go. You have to fix all kinds of things but in most cases it's replacing the stuf that's sub-par, adding a much better valve job, and getting the chambers where you want them. Most of the engines that make these figures will peak at or around 6500 ith a torque peak closer to 4800-5K. That being said - they make plenty of torque right of idle. If you haven't driven a good stroker small block in an A body - do so. I personlly think it's the best street brawler a Mopar guy can get right now. Hands down. They're just that good. On the cam - you will at least need a solid flat tappet, and if it were me I'd go with a custom solid roller.
