Engine swap advice

check or just go ahead and replace the timing chain and gears,adjust the valves to .010 on the intakes and .020 on the exhaust with the engine hot and as stated switching to a later cylinder head,and also upgrading to electronic ignition........another smart upgrade would be to upgrade the master cylinder to a dual resivoir type for safety and even bigger brakes would make the car funner to drive too! Nuthin wrong with a good runnin slanty....especially with a set of duals such as dutra's or you can make a set like mine
