How much would be left on the table?

Kinda what I was thinking. Reason I ask is I am selling the 5.9 I just built and I am getting a super deal on a set of w2 long valve econos with 2.08/1.65, I just have to have the seats cut for the valves and do the porting. Thats pretty much going to take up my budget, and as long as the heads have both exhaust patterns I was just going to run my 1 5/8 el cheapo headers til I have money for bigger ones.
