Performer or performer rpm ?

Ive one of the guys whos never understood why someone would get the performer intake, when you get the rpm that does the same thing only better...

Combo
305 HO (220 hp version, 9,5, 416 heads)
Lunati 60100 cam - initially wrote 60101 sorry !
Intermediate Headers
q-jet and Hei dizzy

Would you get the performer intake or the rpm ?

I`m building this for mpg but hoping to have 230-250 hp too.

If I get the rpm I can use it later on, if I decide to change the block out to a 350 too, on the 305 I guess the performer would be sufficient, but AM I giving up mpg with the rpm version ?

And do you think I will get more hp with the rpm ?
The cam is listed as a 1000-5000rpm basic operating range. (maybe a tad higher on the 305 - but limited by stock valvesprings)

65 Chevelle, ZZ502 with 11,2:1cr and 242/252 110 cam.
Th400. 3,73. 5200stall.
Best 1/8: 7,058 Best 1/4: 11,17 Best mph: 118,6 Best 60: 1,56
13.6mpg
