Not a major problem, but the exhaust valve clearances tend to tighten between service intervals. Supposed to be done @ 600 and 7500 miles thereafter, so both those are due. They are screw and locknut type, no shims required. Setting the intakes to .006" (mid spec) and exhaust to .009" (loose end of spec) is advised. The valve cover gasket is reusable, just wipe clean and use a light coating of RTV around the 4 half moon cutaways and you are golden.
The EPA tamper proof caps on the carb pilot screws should be removed, thus allowing adjustment on each cylinder for highest idle and best throttle response.
The deep spark plug wells seem to hold moisture...as a result the inside of the spark plug caps attract goop. Left to buildup, believe it or not, can affect delivery of spark, especially evident in wet weather. So....unscrew the spark plug cap from the wire...remove the brass lug...and spring and resistor...wipe clean the inside...reassemble.
Thats all I got for you, welcome and good luck, young fella.
