Time for a rebuild????
Car in question is a 1978sc with 113,000 miles on the clock. Car runs fine once rpms are above 3000!!! Car used to start everytime until I let it sit for four months. Compresion is 130 125 125 125 110 120. There are also two broken headstuds!!!

Many rebuilds are done because you want to, not because you have to. What do you want to do?
I have a 78 SC with 130,000 miles that I use as a daily driver. My compression values are 110 to 120. Porsche says they should be within 22, so by that measure you're OK. Does your car use oil? The broken head studs are probably a serious problem butI don't know how much disassembly is required to replace them.
What's the problem under 3000 rpm? Do you have a starting problem?
