Default stock heads - new valve seals

Finally getting around to these, got these heads like 12 years ago from Bob (Bobs77Vet).... he told me they're perfectly fine but the valve seals are bad... well, there was not much of the valve seals left... LOL... the small O-rings were dry rotted and crumbled, the umbrella seals crumbled as soon as I tried to pry them upwards... ... no wonder it was burning oil

So I cleaned these up, pulled out the pressed in studs, installed the screw in version.... new seals will be installed later today when Amazon delivers....

Thanks Bob, I think these will work great on my stock 350 rebuild

Did you tap them manually, or set them up on a mill?

Looks like this new car will delay the convertible build.

I got this stud removal tool that is alsi an alignment tool to get the threads strarted srtaight. No need to drill, the press in holes just a hair over 27/64", perfect for the 7/16 tap...

the tool is $15, the Pioneer studs are $15 (Summit) and I bought the tap for $12 on Amazon.... cheap good upgrade for stock heads, heard these pull out often if you install a cam ... so this is a L48 bottom with flat tops and the supposed to be better 882 casting heads, Edelbrock Performer cam... should run ok... just a little better than the stock 200 hp 😂👍😂👍

I think they came off your engine in the Vette.... you said they are perfectly fine but seals are bad so you burnt a lot of oil.... well, there were no seals left LOL LOL
