what heads to run on a 273

btw, im not trying to dog anyone, just wanna know wether they are reading and repeating or wether they've had a look and actually flowed them to say.

if you put them side by side, you'll see it right off the bat.

btw, no 318 '302' ,.or any other stock 318 head , is gonna flow more air than a stock 360 head....and no way is a closed chamber alone gonna trump the 35 cfm that the 360 head has over the 318 head.

318 wether 302 or 675 flows around 175 cfm
360 small valve head, any of them..flow around 210-215 cfm

i just want people to know whats what.

Maybe IQ52 can weigh in on this?
