J head 1.88 vs 2.02

the reason mopar went to 2.02 is because chev used them in their 327 and 350. called keeping up with jones's . the 1.88 flows very well, has better port velocity. the chev head 1.94 does same versus their 2.02 valve. port speed is what feeds the engine. in real world of stock and superstock, the 1.88 340 and 360 are damn fast. they are factored higher or about the same versus the 2.02 340 engines. horse power numbers sell cars!!!
