    514032 - JEGS Small Block Chevy Cylinder Heads is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from The second set was good First set they sent me had header bolts that went into an exhaust port. They sent me another set that was good but I wish they would have sent me the new set with a call tag to return the first set instead of making me wait for them to receive the first set before shipping out a new set. These are a nice looking set of heads.The only thing I'd like to see them do is debur where the valve guides enter the exhaust ports. Looks like I'll be doing a little clean up there before installing. All-in-all based on looks I'd buy them again.

    Will these work with a solid flat tapped? 11231210 Howard's cam 530 lift

    Asked by: Chippa
    We don't carry Howard's cams, so I recommend calling them and asking them if these springs are appropriate. Here are the seat and open pressure specs: 135# @ 1.800" 340# @ 1.200"
