Unfortunately no, but it should close to factory numbers plus the little bit of head work and slight increase in compression. AHP says it should be around +15hp on a stock car but it'll shine when someone puts a cam in it.
I was paranoid about the factory valve guide concerns, so I preemptively did it to protect myself. The car never showed any signs that the valve guides were bad, but I made sure that it was never going to be an issue. The added performance potential was icing on the cake. I originally bought the car with intention on building it to ~580rwhp and keeping it forever, but life took an unexpected turn.
