350 head ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jostrans68 · 01-17-2005, 08:39 PM

got everything hooked up ready to run fired right up (should have guessed problems) it appears my # 1 valve is sticking . these heads have been siiting since they came back from the shop. And of course it was a few years ago. Have any of you guys gotten a bent valve back in a set of heads? I may just buy another head dang four yrs and getting close this sucks. sounded good for the 1st 20 minutes though. any one got one good head to bolt on close to washington state? lol thanks Jack

I would try running some upper cylinder lube through the carburetor unless the valve has already hit the piston. It might just be sticking and will free up.

hasnt hit piston but I can see it stay down and its stiff enough to bend a push rod thanks

Try pouring some ATF in the carb at a high idle. Not much, just a trickle and have the engine fully warmed up and running at about 1200 RPM or so.

If you need a pair of heads, i have a pair of #624 heads with about 25,000 miles on a rebuild. They are fine and not cracked.....76cc, but 1.72/1.50 valves. Hardened valve seats too. $50 plus shipping and they are yours if you want them....shoot me a PM if you need them.

I have a set that I just pulled to replace with early fuelie heads. I am in olympia and you can take a look at them if you are interested.

jostrans68 · 01-17-2005, 10:52 PM

what kind of shape and price? hoping to find a bolt on one thanks

vk_chevy · 01-17-2005, 11:04 PM

I think they are in pretty good shape with Erson springs. You can have both for $75.

jostrans68 · 01-18-2005, 02:36 AM

by chance do you know the casting numbers? sorry to be a pain Jack

vk_chevy · 01-18-2005, 10:02 PM

looks like the casting number is 462624, granted, not the best flowing head that GM ever made but is fine for those that are not looking to break any speed records...
don't get me wrong, I am not trying to dump these heads on some one, I've got 2 other motors that I'll be building in the next year or so and I can use them myself for those "stock" rebuilds
