Alright, I've heard alot of people claim that these heads are too big for sub 416" motors but its all relative to the RPM that your turning. How much RPM would you say would be required with these heads on say a 394" motor. I can understand the too small cid vs. too big of a head on a street motor but what about the guys that dont care about street driving. These heads look pretty killer.

Those look like the heads to have...and they are available, right Ryan? I ask because it seems like all the really good small blk heads are hard to find...like the W5, 7,8 etc.

ummmm, its the block that dictates 48* or 59*, most heads will go either with some work...ie grinding for the pushrod hole. Im pretty sure that its easier to make these heads along with any performance small block head to go on to a 48* block with out a problem, its just the large runner inhibits the 59* option on w8 type heads..

These heads are being done for a new motor my uncle is building. It will be a siamese bore tall deck 59* r3 block. It will be 439ci. 14-1comp, roller cam on alcohol. It will be going in my new drag car. A 69 dart 3000lb, ladder bars and coil overs 29.5x11.5 tire. Converter will be bought after dynoing, 727trans and a dana 60. What do you think it will run at 200ft above sea level. 
I would bet that seeings how it is a dart it will only run mid to low 10's on a good air day. If I was you I woulnd't waste my time or money on a dart. Just my opinion.

Of course, but the point which was kind of already made was, if you're gonna use a 48° block, why not use w8's for the same price. . .
Don't get me wrong, I already have a set of Indy 360-2's so I'm not bashing them. They definately have their place. . . But it's just not at 9300rpm on a small motor that's all.
59° heads will go on a 48° block, but the push rods end up in between the intake and head mating face. Kind of makes for a pain in the *ss to seal the intake. . .
