I've got a set of heads off of an '87 Blazer, 350, TBI. I know its got 1.95/1.55 valves, but what I really need to know is the combustion chamber size and if its worth it to have the heads opened up to larger valves. Anyone got answers? Or maybe a slap in the face? I've got 487x heads on the engine right now and want to increase my compression. Thanks in advance.
