"Customer brought his nicely kept 911SC to us in 2014 for sorting and mechanical detailing through 2015. We went through the car and completed the refurbishment of the interior, exterior (including targa top), and wheels. We turned our attention to the motor, where a compression and leak down test revealed worn valve guides. We removed the engine from the car, disassembled the top end.
Our machinist rebuilt the cylinder heads, installing new valves, guides, and seals,. We completely detailed the motor to original factory look. During the rebuild we included upgraded seals for the rocker arm shafts, new head studs for the block, and a safety "pop off" valve for the injection. The parts list is quite extensive.
Throughout our work list, every task was performed to return the car to original pristine condition."
