Aloha,
I have an Edelbrock Performer 289 manifold on my '68 GT/CS 289 engine with the original cast iron cylinder heads. I'm using ARP stainless steel bolts to attach the manifold to the heads. I've used the directions provided with the manifold to torque the bolts in the correct order and with the correct torque. But, they keep coming loose after a while.
Are there supposed to be lockwashers under the bolt heads? (There are just flat washers there now that came with the ARP bolt set). If so, what kind of lockwasher?
Or, should I use something like blue (removable) Loctite on the bolts?
Thanks in advance,
Harry Z.
