anybody done this already, im about done and am hoping its gonna work fine. i just used about a 2" grinding wheel i found in my toolbox and starting cutting down and raised the "eyebrows" on the stock reliefs in the piston, then after the four were done i grabbed a little playdoh from my niece and put a little inside the cut away and installed the edelbrock head and the intake pushrods with 1.6 rollers and tightened them half a turn then slowly turned over the engine with a ratchet. after removing the heads i had atleast an 1/8" of playdoh left between the piston and the valve. new to clearances in smallblocks and hope like hell its enough room. anyone with any suggestions or if you think im crazy let me know i havent fired it yet and will listen to anyone who knows better, thanks guys
