81 86 Cutlass Supreme

I've searched the web over a few times and even made some phone calls, but no one can give me a direct answer and there source.

From 81-86 did any Olds Cutlass Supremes have a 305 with center bolt heads ?

Hi Renegade # 51, hello everyone,

Your machine shop should have the correct answer and the documentation, if applicable.

After degreasing my engine and getting the block casting # I found out my Olds had an 86 Chevy 305 this confused me because the center bolt valve covers said Oldsmobile on them. Then I discovered the valve cover adapters. As of now it's in a machine shop being freshened up. Thanks for the reply.

Hi all,

While reading the latest post, I discovered a typo I made earlier.

In an effort to ease any confusion I posted a link to the crosspost.

At the time, no one questioned why my link was back to this thread.

In case anyone someone actually cares, it should have been this one,

One cannot correct a mistake, if one is not made aware of it.
