i ran a set of comp cams xe274h on mine.. they are non-pi stage 3 cams.. they work really good on pi heads.. will keep about the same lift, but give you a lot more duration.. never had a problem with valve clearance, idle, cruizing, or tuning.. sounds good too.. i added 2 deg. timing with those cams and gained about 50 rwhp.. they also work well with a supercharger or nitrous and will see even more hp gains.. and also, you wouldn't have to change your springs with those cams either.. you can talk to a tech at comp cams and they will tell you the same thing i'm telling you.. go with xe274h, you will like the sound and performance..
