Hey guys. I am building my block and was told that the "MR" vs the "HR" head bolts were stronger and are suggested to be used up to 700whp. They are actually what nissan uses in their Juke.

Anyone else hear about this?

Also, How much better, if at all, are the moly coated race spec rod and main bearings vs the oem bearings? Anyone foresee issues going with oem bearings?
