Like said in a previous post 461X heads flow a little more than the originals, they are also twice as hard to find these heads were only available from 60-63 and are 172cc intake runners with 62cc combustion chambers instead of the original 64cc. Another great factory head is the 041 or 041X, these are the exact same casting(intake runners and combustion chamber design) as your double humps but have a right angle triangle instead of the camel humps. The X means the same here that it flows better. Just my 2 cents...........

69 is large journal

the camel hump 1.94 heads were most common...yeah, they were on the 300 hp motors

as usual, you have to pull the heads to see what you really have, a lot has happened to many pairs of heads over the past 40 years

Great post RACEFAB. I'm left with a question though. In referencing both the larger 2.02" intakes, and the larger runner area of the 461x, you've stated that they "flow better." This may confuse some folks into thinking that bigger is always better. In this case, bigger usually equates to a significant loss of port velocity throughout the majority of the powerband until the revs really get up high.

mmmm, havent seen this thread in a while, will have to go back and read thru, but I dont think I said that the 461x's "flowed" better... I think i said they have more runner volume....170 to 175 cc on the ones I have cc'd compared to the 160cc of the stock 461



I also touched on how a smaller 1.94 valve could actually outflow a shrouded 2.02
