12558062 Vortec heads
Will 12558062 heads bolt up to my 1976 l48 350? My research so far says they will. I am following up here as the next step. Any clearance issues with the intake and carb? Stick with the qjet or go with edelbrock? Thanks.

Assuming your Q-Jet hasn’t been hacked by someone along the way, I would stick with the QuadraJet. The 1976 QuadraJet has over a decade of engineering refinement added to it vs the Edelbrock.

Like Shark Racer said, yes, they will bolt right up, but you will need a Vortec specific intake.
I wanted to run an RPM Air Gap intake on my 74, but ended up buying an Edelbrock Performer EPM intake for my crate 357. I have yet to install it, but hoping for the best.
The EPM shows pretty decent numbers for a “low rise” intake, and are nearly an inch shorter than the Air Gap (if memory serves me right).
There are mixed feelings between QJet, Edelbrock and Holley. Personally, I like Holley carbs as they’re simpler to tune, but I hear that once you get a QJet dialed in, it’s there and runs GREAT!
Best of luck!!

Thanks to the guys who responded with good info. I was able to purchase these 062 Vortec heads for $200. They are able to handle .500 lift and have Z28 springs. Magnafluxed and cleaned.

[QUOTE=Fatpig;1605359836]Thanks for the info. I found a really good video on youtube that explained to me why this is a god idea. I am definitely going to do this. https://m.youtube.com/watch?v=ejih8y7wli4#menu
