anyone have a .513 lift cam and stock heads?

I havent fired it up just yet,but it really isnt too big of a cam.It has less duration at .050 lift than the mopar 509,and the intake lift is only .494,so i dont see any problems with clearnace issues.I did order edelbrock torker valv springs,so i wouldnt need the extra machine work.They are single with a damper,and the specs are close to the same as what lunati calls for.Oh,and they were only 69.00 compared to the lunatis 110.00 at the time i purchased them. http://store.summitracing.com/partdetail.asp?autofilter=1&part=EDL-5777&N=700+0&autoview=sku Oh,im using my factory non adjustable rockers until i get some better roller rockers or something,and i dont forsee any problems with them.
