just been building my zete cturbo the night and when i came to bolt the ARP conrod bolts i noticed the star sockets ive got dont fit the ARP rod bolt heads

anyone shed any light as to what socket i need to get hold of and buy? and where from, Burton?

also it says to stretch the bolts by tightening them to 27lbft, then slackening, then torqueing to 27lbft, then releasing, then torqueing one last time to 27lbft

following the stretching procedure, i assume i then just torque up the bolt to Ford spec?

cheers
