Arp bolt and performance plumbing question

[Brian O Conner]

Now I bought arp head studs and a main studs kit but is it absolutely needed to get performance bolts for the Cam bearing caps, exhaust manifold and the intake manifold? Also as for the plumbing is it absolutely needed to re route the vaccum lines if your goals are planning on running over 450 hp on high boost?

Thanks community

you dont have to use everything arp i mean it would be nice if you can but for a 450 hp application you should be more than good there are a lot of guys pushing more hp with almost every bolt stock except the headbolts
