Should be pretty reliable for a DD depending on tune as well. It's all about tuning, that's why some people can run 22lbs and not blow a motor, and some people can run 10lbs and blow a motor real quick.
you are a moron. please dont listen to this guy. first things first.
A) low compression on high boost is not better than higher compression on low boost. if you can make 300whp on 9psi with a 10:1 ratio or 300whp on 14psi with a 8:1 ratio, guess which will be faster? the high compression since it will not only spool faster, but not have to spool as much. your an idiot for that comment.

B)um there is only one head. not "heads". and absolutely no headwork is needed to make 250-300whp.

to the real world. get your **** straight before you post.
