Overheating....head gasket i believe

" The cause for this is inferior quality OEM cylinder head bolts. The factory Toyota bolts do not provide enough clamping force to keep the cylinder head tightly clamped against the block so, over time, the bolts stretch and the head gasket blows out."

I am LITERALLY quoting what jscspeed.com says at the top of the ARP headbolt page

Is this ACTUALLY true or are they just trying to wean me over into spending more money on ARP Head bolts?
NOTE: My car is a NON TURBO. i do realize this application is only for the 7mgte
