Billet Rocker Arm Retainers

[kangarooboy]

I'm rebuilding my cylinder head, BMP has billet rocker arm retainers, they look kinda cool but is there really any benefit? Could my $100 some bucks be spent on something else?

The standard retainers are quite light and I have not seen any fail. Ultimately aluminium/titanium retainers are lighter and may allow another few hundred revs before valve float at 8500+ with a large cam, but when you get to that point you are usually throwing thousands at the motor for small gains.

Spend your money on some decent valve springs instead.

He's talking about the clamps that go over the rocker shafts, right? You can get them cheaper through Ireland Engineering if you really want them, about $8 each.

it's a good idea.

Probably not necessary on a daily driver, though.

Spend the $100 on a more agressive cam grind!
