Trying to find the collector sizes on different headers for the 302. I haven't done my swap yet but I have a 1990 Lincoln mark vii with a H.O. 5.0 I am going to use and R2 tranny. I also have a pair of pro comp alum heads I bought for a 351w project I am doing for the mark. But I've been thinking of putting them on the 5.0 for the ranger. The exhaust ports measure about 1 3/8 x 1 3/8. So this is my concern I don't want to buy headers with to small primaries that it chokes my exhaust flow. Right now the motor has a set of early 351w heads hand ported and the stock shorties are definately a restriction.
