    514022 - JEGS Small Block Chevy Cylinder Heads is rated 4.4 out of 5 by 5.
    Rated 5 out of 5 by from Best heads for the price For the price you can't beat these heads. Look up who makes these heads for jegs, you won't be disappointed. Unless you have the extra $700 for AFR heads I would get these over all the other budget heads. Jegs shipped fast as always!

    Rated 5 out of 5 by from Great product 2 years now with these heads on my truck, and zero issues. Look into these heads and you will find whom makes them, in my opinion this is the best head for a sbc next to an AFR, but Almost half the price.

    Rated 5 out of 5 by from High quality I bought these a while back for my sbc 350 in my 72 chevelle and these are everything I hoped for and more. I got them when there was a temporary sale at $499 each I believe. Nothing like having a nice new set of aluminum heads that also perform GREAT. They're worth every penny!!

    Rated 5 out of 5 by from Good to go I had heads flow tested before installation and found to be 8 to 10cfm average lower than advertised. However I had 5 angle valve job and the bowls polished and gained average 35 to 40cfm increase. The cylinder head shop was very impressed as well with these. They have received other brand name heads 30cfm lower than advertised, which was good to know.

    Rated 2 out of 5 by from Take head apart check everything Don't just bolt them on, take them apart. Had metal shavings in ports from casting, oil drain back holes are really small ( less than 3/8"), they say .525" max lift but I'm at .490" lift and I can't get .060" feeler gauge between any coil at .490 lift. Haven't run them on engine, not saying there bad but theses are the issues so far.

    Will this work on a olds 307 

    Asked by: Romanranes
    No, you will need an Oldsmobile head for the 307, not a Chevy head.

    What length push rods do i use

    Asked by: Boxheadflea
    We recommend this type of pushrod, but you will need to measure to get the proper length. http://www.jegs.com/p/JEGS-Performance-Products/JEGS-1-Piece-High-Performance-Pushrods/1558358/10002/-1
