Hmmm I wouldn't do headers unless there long tube. You can search on the forum forthem but all the work it is to get them in theres very little gain and its only at the top of the flow around 5900 rpm and it was charted at like 4-5 whp. But long tube u get double on the top and you get more low end but good luck with finding someone buddy..
