Which Headbolts

[Chris H 10]

What brands/part no's does anyone recommend for a competition xu5 engine?

 

The engine i've got currently has the torx head bolts but without the spiral "stretch" pattern, they just seem like a normal bolt with a slightly waisted shank.

 

Are this type better or are the ones with an obvious stretch section the ones to go for.

 

What about brands? FAI, Ultra, Victor Reinz, Payen etc

 

Cheers

Chris

ive used a few sets of Payen bolts without any problems at all.

 

FAI I have used in iron block engines in the past

 

v-r is a federal mogul brand iirc and they make a lot of o.e stuff.
