If given a choice would you guys get the RPM
Aluminum heads or get the Roush 200 cast Iron ? The RPM`s are about $80.00 more and are of coarse aluminum...But it seems that everyone thinks the roush heads make more power,but they are cast Iron.These heads will be for my 306 and eventually be on a 393w
both are street and strip ,pump gas engines. My current 306 set up is outlined on my web site...click on "1972 Maverick" ------------------

first Q : where do you live?If it is cold, the alums will leak. The aluminum expands and contracts at different temps than iron (your block) and by different amounts. In most cases iron heads make more power, where aluminum is lighter and can stand i higher compression ratio to make up for the difference

RPM!period. . .
Get the weight off the nose and great quality too. Nothing against the iron heads, but they are still just iron heads. 
BTW, when we have frost on our windows we run the hose on them to clear it off.  SteveW

Our plumbing is run on the outside of our houses here, at least to the outside hose bibs. We did get down to 22 degrees a few years back and I had to replace the outside pipes. But usually we get frost on our windshield about 10 times a year and it's only about 30 for a low. So we spray them off with the hose and away we go. SteveW

It's cause some folks think that aluminum heads aren't good in cold climates. SteveW

MAV,I'm not sure about the thinking that Alum heads aren't good in cold climates. What I do know is that they ROCK in our climates!  Get the RPM's or Vic Jrs and don't let your engine overheat. SteveW

Mav, Think about header clearance????Spark plugs access with the Roush's can be a little problem? There's a set of Edelbrock's fully ported for $500.00. ------------------

Beware that the cheapest Roush heads have really weak valvesprings.

From Summit's websitePart # WRL-053040-1 Assembled Roush 200 heads have 1.25" diameter (seems really small) valvesprings
Proce $419 each Part # WRL-0503040-2 Assembled Roush 200 heads have 1.437" valvesprings.
Price $479.50 each FWIW my local speed shop refuses to sell the small spring heads after a guy fragged his engine with a dropped valve at around 6K rpm.
