Valve Tip/Rocker Height Question??

sorry if I came on too strong, but dealing with the general public some times people think just because they paid hundreds of dollars for a tune up they should get a extra 50 hp/plus 100 mpg. in by experience the stock 360 cam is one of the best cams for the 318 with stock gearing. most people want a big hemi grind , but with the thick head gasket and the piston down in the hole your still near 8.5 to 1 comp. and just a mild performance cam is too much. the one I'm talking about is .424 lift .good luck and yes I over camed everything in by youth listing to experts.
