Magnum vs standard head pix
Anybody got a good side-by-side pix of two heads to show the difference?
There's a pair of heads on ebay but seller doesn't know difference and his pix don't show the exhaust ports. Listing is "CHEVY/GMC 63-73 401 351 V6 TRUCK CYLINDER HEADS" All he says is "These heads fit 2 ton gmc truck with a industrial v6 engine" If there was a good pix to send him we might find out which he has. |

If those are the ones listed for $800, I wouldn't pay that price whether they were magnum or not.
But, if you google gmc 351 magnum, click on the images tab and I'm pretty sure someone has a pic on there of them side by side. |

That's what I was looking for!
And no, not for $800, even if they are Magnum "just as good as new" heads. http://i226.photobucket.com/albums/d...ictures582.jpg |

Yes, a good pair of used Magnum heads should go for ~$200.

Reply from seller:
"The only markings on the head is the casting number the date code and a M.The intake gasket listed for the magnum has the same pattern as these heads.If there is another way to indentify the heads i will be glad to ck it.Thanks" Does the "M" mean "Magnum"? I might have to consider making an offer --:confused: |
Re: Magnum vs standard head pix
The best way to determine which heads they are is by the part number cast in the rocker arm area, 66-72 magnum heads will have part #2421158, 73-74 Part #696030 or 696031
