:thumb:i put a 20r head on a 86 22r block and had great results. i had the head cut down, stage 4 port and polish, large 45.5 intake 37.5 exhaust valves, bigger seats, pro viton valve seals, dual valve springs, titanium retainers, stage 4 comp cam, holly street dominator intake manifold, holly 390 cfm four barrel vacume secondary carburetor, all of which was purchased from lc engineering, holly fuel pump and regulator, headman headers, 2.5 inch exhaust straight back to a summit pro flow muffler, msd 6al ignition, msd coil, and Taylor 8mm wires. after all of this work (mainly ripping out vacume and smog stuff) the results were excellent. i am now able to spin the tires through second gear and it feels awesome. if any questions about this topic arise let me know.
