Interesting, i didn't know Edelbrock moved the valves on those heads. So i assume they need a new shaft rocker system so rockers/valves stay in alignment?

Lol , there not moved enough to need a new rocker shaft. Come on man you knew that ....

I had no idea the valves were moved or how much they were moved. Any info what was moved (intake or exhaust or both) and how much? Sorry for the hijack |

I thought you were questioning the fact that they flow 20 CFM across the board better then drags heads ? Whats with all the other questioning? If you call Edlebrock they will give you all the info you're asking me... I tell you what . Dave does good work . I saw them up close!

Ok.... ill bite.
The exhaust valve was moved 0.060-inch farther away from the intake valve, which resides in the stock loacationThe spread allows for the installation of a oversided intake valve. This was done in 2012 , you should know this stuff !

Why should i know it? Edelbrock never mentioned it that im aware of and it's never been discussed here that i know of (if it has what thread? Not finding anything by searching). I will look into it.

It states the spacing is 2.030. So there is .020 between the valve sizes you listed. Thanks for the info, appreciate your help. |

Funny I get made fun of (by internet experts with no turbo or centrifugal experience)when I suggest that bore stroke being ideal for our Pontiacs.(actually 4.255 bore is better cause then it's a 455 lol). Besides better cyllinder seal it's less side loading without excessive peak piston speed. NA go ahead with bigger bore. Still personally would like to use rpm to replace stroke NA but to each his own I guess. |

Point is they flow 20CFM better , I say you seem to be questioning . That which has nothing to do with if or how much the valve was moved and it needing a different rocker shaft when it doesnt...
