Technical anyone using a stud girdle with Corvette valve covers?

a lot of the NEW ones have extra room under there now days

 

Call him he just might accommodate yo9u woith 7* ones


ha spelling 101 you (with out the 9)...lol

 

another thing, I am not running aftermarket heads on this, I am running angle milled 461's, you are USUALLY ok cutting them to 1.55, but I have heard of the spring seats in camel bumps cracking after a while when they are cut for 1.55's. Sometimes its fine sometimes not, probably depends on core shift. I'd rather not chance it if I don't have to.

 

Honestly I prefer new springs.

 

Thought he listed as NEW

 

For the price Summit has on the K-Ms, I would pull the trigger.

 

the 461's if/when cut do slice into the water ,,, ya MUST cut above with shims in place / in the pocket.

 

Yea, but I got a 40 year ac***ulation of ol' **** I gotta use up...

Yes, I drop a .030 shim on the seat. But even if you don't actually hit water when you cut them, they sometimes crack right in the corner of the radius after you use them for a while, which is big pain in the *** when it happens after you have 40-50 hrs of grinding in them! I've run 1.55's in camel bumps, but I prefer not to if I don't have to.

 

I had to look again. Holy ****, you are right! I just ***umed he was selling used stuff, $150 for new PAC springs and manley ***aniums is CHEAP! I will look into that, thanks for the tip! Man, that's really cheap!

 

461's on the OUTSIDE corners were the worst..
we just furnace welded them and jump in like a beaver cutin em.

Edit ALL the spring pockets.

 

Yup, that's where they would crack if they did. Where did you work? Were you at CHA or something?

 

Its KQQL its a HAMB thing....
I'm down to MOSTLY doing some BS fancy painting(nobody EVER wants to pay you what your worth) AND valve work, for the PQQR stock / drag car boys,
I'm retired so i can do, or NOT do...lol

 

Man, you know, I was just thinking, if you REALLY want to know something about getting serious with camel bumps, theres a pretty good wealth of info on this thread.

 

WE'RE like the govt. we're here to help.

 

With all that info, which some things I have not tried, and my "pocket " was more accomidating, I would go with your choice.. some things aren't meant to chance, even though you could....... I think the ( your ) spring choice is a good one, and will suffice with the #'s, and diameters. Saving the pocket, covering the cam, and so on.... Rock On!

 

1.6 's big block O.D.'s in some 461's on a 283 back in 1972.
Life is a bit easier buying stuff (gotta love that word stuff) right out a the box these days.

 

I was still ******* myself randomly, and my 461/462 info didn't arrive until a lot later!. But glad you did it, and have the t-shirt!

 

and angle milling those same heads , (none were available to BUY in 1972)after plugging the cooling holes, then milling them down to next to nothing , there was about 1/4 inch left tween top of bolt hole and surface.

 

YIKES!!!

 

Wow just got back on

Thanks for all the info. ( a lot of smart guys here )

Have 2234002A Top-Proline 220 heads with a Howards mech. roller cam that Compe***ion Products recommended about 10 years ago. (Heads are cut for 1.437 dia springs)

Current valve springs are Howard 98441 installed @ 1.750 with closed pressure @ 175 lb
open pressure is 400 lb @ 1.150

Looking for a 1.437 valve spring / retainer pkg with installed height @ 1.850 so there may be enough room for
.681 lift using 1.65 Howard rockers.
Cam spec.s


Freshened the engine, bolted the heads back on yesterday.

Norb

 

I was washing Brooks pistons and rods and pushing a broom around Bob Crosbies shop at that time. And watching him screw Booth-Arons heads onto MP and gas cl*** motors...I saw some pretty trick **** in those days.

 

Norb, what are you shifting it at with those springs? Do they last good?

 

Running a glide shifting @ 6900 rpm, going through the lights @ 6300 rpms

Never had any trouble with them, I should replace them any way 10 years old.

 

Thanks Norb. 10 years on the same springs! Hell, nothing wrong with THAT!

 

Norb with those heads you should have no problem cutting the spring seat for a better spring package.

 

After larger springs installed, no room would be left to get a socket on one head bolt.
( 1st bolt in the torque sequence )

All ready have to use a skinny 3/8 drive socket to jam between the springs.
