When I've looked into pistons for a 318 they was never a year specific mentioned as they all are the same, I know that there are different compression height's but all direct replacement pistons that I've found are still down the bore except for the kb's which have a 1.800" compression height. Am I looking in the wrong place for pistons? If I could get a decent compression ratio by using a replacement piston and still be close to a zero deck height that would be better. I'd like to get away from the pistons being so far down the bore
