I am looking for the cheapest shop in the greater Philly area to have my head gasket and timing belt done. Price is extremely important as this is a very low budget auto/build. I've found a place in NJ that will do it for $1675.00. Is this the lowest I'm going to find or is there someone in the greater Philly that will do it for less? Any help would be appreciated!

My car is a Porsche 914 with a JDM 2.0 Subaru twin turbo engine and manual transmission.
