WAS re. octane question IS what octane per cam

[Pedro Faria]

I'm in the midst of installing a 276 cam on my NA 4kq, and while i'm in 
there replace lifters

what fuel should i be using after the installation , in the past i have 
always used 87 oct, and once in a while injector cleaner

TIA
Pedro
