arp struds or studs or watever, wat are they, what do they do and do i need them for b16a t3t4@10psi 250whp?
thanks

 

annybody? sorry for not knowing this but i never heard of it b4!

 

APR head studs? They are the large studs (similar to bolts) that hold the head on the block. APR is a brand, and are stronger than stock when installed correctly. If your having problems with your head lifting, it might be time for an upgrade.

 

its well worth the money for headstuds.

 

so i dont need for my application? only for 14psi 300whp or so?
