The camshaft installed, the double roller timing set is installed. Make sure the oil galley plugs are put into the block first, otherwise you might forget and have a huge internal oil leak. The camshaft is "degreed" or checked with a degree wheel to make sure it's installed as it was designed. In this instance, I had to use the 4 degree retard position(after the photo was taken, since it clearly shows it straight up, or at 0 degrees), and installed the 112 LC cam at 110.5, or 1 1/2 degrees advanced, primarily to counter the affect of the timing chain stretching.

The heads then get a treatment similar to the block. All surfaces masked, spark plugs holes included, intake surface masked and trimmed to match the intake gaskets.

The Fel Pro 1027 head gaskets are set onto a carefully cleaned block surface, and the head surfaces are also cleaned to help insure proper sealing. Then they are bolted onto the block with a new set of ARP cylinder head bolts and torqued according to ARP instructions, using a high quality pipe thread sealer on the threads since the head bolt holes go into the water jackets in the block.

Once Dave decided he wanted a roller cam, I suggested changing the original dual plane intake to a single plane, figuring it would work better with higher rpm. I tried a Dart single plane intake, but it would not clear the ridge on the 990 heads, so I spent a few minutes thinking about grinding the edge of the intake,, or removing the heads and grinding them,,, wasn't excited about either. I had offered to get the Dart intake polished, but Dave declined, so while I was looking over the problem, I decided to get a polished Professional Products intake that would compliment the look of the new Quick Fuel carb, Rex stainless steel scoop, and fabricated Obnoxious Racing Engines valve covers that still had not arrived.
