SPS bolts?

Whats the deal with the factory SPS head bolts?

I was told the factory SPS bolt are much better than the ARP Bolts. I remove a full set of SPS bolt from my 87 motor. this project is really coming along SWEET. i was able to drill the #2,3 and 4 main with a 3/8 X 12 drill. i also drill the two lifter gallie with a 9/16 X 18 drill. the passage in the lifter oil Passage way is bigger and so is the main journal. I am not getting the HV timing cover and oil pump plate. i will also see if i can do any modification to the timing oiling passage way.

so what do you guy think of the SPS or ARP bolts?

thanks.

I didn't know you could buy SPS head bolts. I know stock rod bolts are SPS. I thought the stock replacement headbolts were torque to yield, and I don't know what brand they are. ARP head bolts are not tty and can be re-used.
