hey guys just another quick question,
the 5k i just bought has a 5k head but was once running a 3k bigport head and running a 10.9:1 compression ratio.
the 4age pistons have the valve rececces in them so I'm just wondering weather its worth trying to find a 3k bigport head or just shave the 5k head and do a big port on it.
what are your thoughts??
cheers again guys
