The 1964 427 Hi Riser engine has 2.197 intake valves and 1.725 exhaust valves. Does the NHRA (Dave Wren Hemi) rule still say Plus .005 and minus .015 tolerance allowed ?

Yes, it is still +.005/-.015. The valves were 1.728 when they went in the heads. The one in question had been pretty deep in the seat and pushed an edge up to the margin.
