I'll try allen head bolts this weekend. Thanks for the suggestions. It's annoying that the design of the manifold didn't account for this.

Be thankful you can't get the valve covers off without loosening the exhaust- either that or your next post will be "how do I get stuck headers off- I rounded the seized bolts!!"

Thankfully that shouldn't be a problem as I used stainless steel 12pt ARP bolts coated with antiseize (stainless into aluminum). Actually, I usually have to retorque the bolts a few times a season, I've actually had a couple work themselves loose and fall into the bilge.

I had the same problem with my Gil exhaust. After installing exhaust spacers the problem was resolved. I also use Eddie Marine valve covers that I use studs on the exhaust side and the long polished bolts on the intake. Try to change spark plugs is a different matter. This is a project that requires patience and a large quantity of beer! Randy

Someone, somewhere, makes an aluminum "bridge" that is about 1 1/2" tall and spans across all four lower valve cover bolt holes so that you only have to use the outer two bolts. They look like they would work on any valve cover.
I have these on my motor, but they came with the boat. They do not look home-made. I have short studs in the center two holes that help keep the bridge straight and gasket in place, but are less than 1" tall. You put the valve cover on, then slide the bridge in between the cover and the manifold from the front or rear, drop your two end bolts in and your done. Have never leaked a drop. I love 'em![Big Grin](/forums/images/smilies/biggrin.gif)
PS -- I have gil manifolds and older type alumn covers.
If you click on pictures to enlarge, you can see the black bridge against red part of valve cover....
