Quick block dowel pin question

[FastGS-T]

Alright aparently my machinist misplaced my dowel pins while checking my block. Do i have to have them? or can i just assemble

if i have to have them what size do i need or does sbr or extremepsi sell em?

 

[BogusSVO]

yes you need them, they align the block, HG, head

the head bolt/studs will not keep them close enough.

 

[rlacasse1]

Yes, absolutely. Listen to Bogus, he knows a shit-ton, especially when it comes to machining and crap.

extremepsi i have some but they are kinda beat up. The dowel pins for the transmission side are important for clutch alignment.
