studs are overkill for n/a. i got them like i said, for a smoking deal, and i plan to boost later. bolts are more than sufficient 99% of the time, if not stock bolts, then ARP bolts.

a reconditioned head should have been milled, new cams/reground cams, new valves, retainers, keepers, springs, buckets, shims and all checked to spec.

call them an ask them what their reconditioned head includes. if they cant tell you everything or shrug their shoulders, be questionable.

yes headbolts need to be re torqued after a few heat cycles.. or maybe your shop over torqued them to start with.. don't think thats the best idea.

This was the toyota dealer who fracked up so much, did a lot of freebes to make up for it but still

Do your self a favor and when you go to reoil/clean that K&N toss it in the trash instead and by a good Dry flow air filter from AEM, HKS or even stock.

The K&N are notorious for not only allowing too much debris into the engine... Also there is probably a 80% chance when you reoil it that its going to destroy your AFM.

well ill will be changin that for sure then lol thanks
