i think he just chipped it... when i sent my pistons on vacation to the oil pan.. it sounded alot worse than his vid
beathing mods are headers, plog, downpipe, intake .... your best bet is to get headers. and it really depends on the plugs... if u get a stock pulley on .. go with autolite copper 605 or 606 heat range... if u get headers or a downpipe... get some new autolite copper 104's.my advice is get a mechanics scope and look into the cylinder and see how bad the chip is before u make any further decisions on the car.
