Camshaft - valve hits piston

To prevent the exhaust valve from hitting the piston, I had to set the valve overlapp to 35mm instead of 67mm. Cam is 911R. number 901 105 103
What consequences does this have to the performance of my 2.8 high performance engine?
Dyno test right now shows 180 HP on rear wheels.

thanks, harold
