thats all true,serious power costs serious money,uncommon parts add to that cost,i am not a big fan of indy but look at 600-13 heads even,dont see or hear much about them either,if everybody had a mega block they wouldn't be 4 grand for the iron version,although,kb blocks aren't cheap either and a lot of users there hasn't brought the price down,7700 I believe,out the door,{a year later},I guess opening your mind to options during a build always helps out with affordability/horsepower options,plan,build,adapt,go fast....




The 600-13 is more about the 4.84 borespacing and cam location than the heads.
