Brag to who about it having iron heads? Nobody cares about that stuff..............the fastest so and so with iron heads, so and so valve and 6 pack rods. Truly nobody cares. So as already stated, sell the 6 pack anchors to some resto guy, don't waste the money on iron heads and paint the alum ones orange. More power AND cheaper in the long run
For performance, I agree. But you would be surprised at how many engine builds down at the shop we get for basically that almost exact request! Not to mention, some Nostalgia classes still require iron heads and blocks only. We have a guy that ports all the iron heads and Ron does the seats and new valves & decking followed by a vacuum seal check after the valve job.
Right now we have a blown 331 Hemi all iron in the works....The old style with the bell cast right into the block, and a really small Ford flat head in the hone....People still want the old stuff, and it pays the same either way. We generally get the most requests for a 440 stroker with iron heads. I think Ron built one with iron, and the last two with aluminum. But if its just a street car that never sees over 5800....
So as much as I like the go fast stuff, I would bet the better part of the rebuilds in our area are just this....But then again, they did ask this in the "Race Tech" section and Hemi blocks are tough to get right now.
