Fits perfect
I would say that this is a very good bye I would hope that they would soon with the next set includes some grease So everything can go together more smoothly but other than that I just used my APR grease with it and it worked out perfect If you don't have that I'm sure some Polly grease would work out well

Good 1 torque
To those thinking that these might be good enough to cheap out on vs. name brand. Dont. Theyre not as good as the name brand. Stripped threads and broken stud on 2nd torque replacing a bad lifter.

Shockingly worked
I was not expecting these headstuds to work, they are inexpensive. They torqued down great and have been holding up well on my engine

Complete trash, do not trust
Do not trust these studs!! Used ARP lube and torqued to spec, stud broke off in block and I was lucky enough to get it out, all studs stretched at different rates and very inconsistent torque readings, stud was super soft when drilling out, looked at all the other studs that held torque and nuts where pulled sideways and looked cross threaded and would not come off studs
