Which heads will be good with my build? Looking at AFR, fastburn, bow tie etc
I am considering the vortec fastburn 210's. the GM bow tie, E-tec 200's and the AFR 190's.
I am building a forged L98, It will be fully forged internals and am looking into a dual pattern cam because I want to spray it alittle also.
For a mild 350 which heads would you choose?

If you can afford them, I would go with either the AFR 180cc or 195cc heads. What else is being done to the motor?

The Vortec manifold stock flows about 220-230cfms. That about the same as stock. Not worth it. If you do a major port job to it, it will only get up to 260-270. Dyno Don has this combo with E-Tech 200 and made 370rwhp@5500-409rwtq. Major port work was done but it wasn't worth it. Look at my sig below. This hp is with medium port work and 30 less hours.
Your best bet is the AFR's 195. Make sure your manifold flows 290-310cfms for best results.

I will eventually put a D1sc on it, the block will be fully forged, rods, pistons, crank, I'm just worried the iron heads would lift.
