head choice
I was ready to make my order then I started thinking again. 
I don't want to start a heads war. I would just like to know which set of heads would be better for a daily driver/street rod?
Brodix IK180 or Edelbrock Performer RPM
Thanks again!

I have had the Edelbrock RPM Performer head and the now have the AFR 195 heads. I preferred the AFR 195 head. If I remember correctly the Edelbrock RPM Performer heads leaked when the engine was assembled and we did a leak down test. I called Edelbrock and they said the heads were aluminum and the valves would stamp themselves in. I had the valves cut and re-seated so they did not leak. I also remember the machinist telling me the seats were not standard and they expected you to cut the valves to the specs you wanted. But I am not sure about this.
I know a very knowledgeable Tech rep at Summit. He gives me great advice. Call 800 230-3030 and get hold of technical Specialist Norm at extension 6652.
BTW: The RPM Performer is a great intake manifold to go with which ever head you pick.

What are you future plans for the engine, that would be what I'd consider first. No sense buying another set of heads down the road if your planning more engine upgrades. I have AFR 180's and love them with my setup.

The engine is an L82 350.
The cam I picked out is the Lunati.
I also picked out Lunati roller rockers.
The intake is the Edelbrock 7104.
I plan on using a 2400 stall too.
I guess I better check into the AFR heads also then.
Thanks, Marty

The IK180s are great heads at a great price.
AFR, IMHO, are by far the best heads out there in virtually every configuration...but they're not cheap
In the end you don't need opinions on this stuff...just go look at the flow numbers, I/E ratios and your checkbook and the choices will become clear

The AFR 195's flow the same as the Vic Jr 215cc ( which actually cc'd 219 ) I had on my 406ci which made 550HP. I never thought I would hear myself say this but the 195's are too much head for a mild 350ci. 383-406ci the 195's are a good choice. Now these are the new Eliminators I am talking about not the old design.
Go with the Brodix heads or a smaller AFR head

might be a little off track here, but its something ive always wondered. why isnt there a commonly quoted ratio of individual cylinder displacement to intake runner cc, or vise versa? like 195cc / (350cid/8) = 4.45:1 It would make conversations like this much easier ("nah, you want your ratio right around 4.00 for good low end torque.."). at least thats my thought.
Ok, back to your heads. To qualify my previous post, I do tend to prefer heads that are a little on the large side (AFR 227s on a 383 right now), and since your build is relatively mild, maybe motorhead is right about the AFR 195s. I think they would be the biggest heads I (personally) would consider for that motor, and would expect to see more top end power and less low end torque than the same combo with the brodix heads.

If you read the summit page the AFR 180 is for a 327 to 350 motor idle to 5500 RPM. The AFR 195 is for a 350 to 400 motor operating in the 2000 to 6500 range. Your cam operating range is 1800 to 6200. Your intake operating range is 1500 to 6500. You have a 2400 stall. Depends a lot on your build specs and intended use. A 327 that pulls to 7000+ and sees a lot of track time could use the AFR 195. A street 383 that will never see 5500 could use a 180. Your also planning on using the same intake with either head. I don't think you will give up much bottom end with the AFR 195. Probably stronger mid range and definitely stronger up top. This gets asked a lot on builds similar to yours. Would really like tio see a desktop dyno comparison on your build of both heads.
One other thing the port size on the Edlebrock intake is 1.28 x 2.08. The AFR 195 port size is 1.28 x 2.08
