302 heads...were to buy..what works with..?

That hotrod article is F.O.S to the max.
The flow numbers listed as cast are BS!
The gain listed after the way big valves are worthless!

I get 210/177cfm with a stock valves, HOTROD MAGAZINE IS A JOKE! AND SO IS WHO WHOEVER DID THE HEADS!

They posted false numbers just so the crummy work they did would seem not so crummy.
PATHETIC!

I wouldn't recommend going any bigger than a 1.88 intake valve on any 318 head, the port wont support the flow that valve will.
Another thing is, the port window does not need to be opened up till ur flowing in the 220 cfm range, it supports 215 cfm as cast!

IF ANYTHING... THESE/THAT ARTICLE IS SHOWING WHAT NOT TO DO.

JMO based on real experience
