Gm Cast Aluminum Pontiac Valve Cover Accessories
Hey guys I just bought those new GM cast aluminum valve covers, for gm parts direct. I paid $140 out the door. I am sick of screwing around with those cheapy chrome covers.
They look like these ones. I've heard good things about them.  Anyways I need to buy new gaskets, I looked online at partsamerica.com, 1) they have standard gaskets and the (ram air/HO) gaskets. What is the difference? 2)Does anybody know what breather hole size is for these covers, I know a few guys have them already. I'll need to pick up up at the local auto store. 3)any special tips to installing these bad boy's leak free? thanks guys. |

Mr. Gasket Ultra's are what I use, X-tra thick and cork to boot.
Super weather strip 3M glue to V-cover side and install. BTW; nice covers, I want 'Santa' to get me a set this Christmas!lol Breather looks to be standard size, Moroso makes those and come with the grommets.

Are they tall enough to clear 1.65 roller rockers?

No. They require either spacers or grinding the edge of the forward and rear rocker arms for clearance.

Great looking covers, I had a set but did take them back, they will not clear the 1.5 Harland Sharpe rockers even with spacers, contact was made on the top edge of 2 rockers where the top hold down boss on the valve cover dip inwards, you can check this with a finger through groumet hole. Are you going to put a coat of clear on them to help keep them clean? If they ever would become too dirty I always wanted to paint the entire valve cover and then polish out the emblem and the raised Pontiac lettering. I think they would be an awesome looking cover then, Dave.

All you had to do was grind down the back end of two rockers on each side just a little bit and they will clear just fine. I have these on my 72 with 1.65 roller rockers. No problems at all.

Yes, that would work, it also would void the warranty on the roller rockers, a chance I was not willing to take over a pair of valve covers, Dave.

If those rockers actually need to be warrantied there's probably other things going on in the motor.

Just like to be using parts the way they are designed to be used, I feel that if a fellow pays $190 or even $140.00 for a pair of valve covers they should fit with out having to modify other internal engine parts, don't you agree?

I agree, but alot of parts have to be modified to be used. Every Edelbrock Intake I've gotten has had to be milled to fit. This is a GM part and they didn't design it for that.
If you want the look of a cast Pontiac valve cover the options are slim. The rockers can handle that that cut off and not affect strength. |

Those valve covers clearly state they are for stock valvetrains - aftermarket aluminum rockers aren't stock - they work exactly as advertised. As an FYI, I am using them with stainless 1.65 rockers. I need to pull off one of the covers now that I've finished the engine break-in to verify there hasn't been any contact as even they are very close to the bolt boss.

Let us know how it turns out. I plan on using Crower stainless 1.65 rockers and would like to use these valve covers.

The boss they rub is all the way up so I don't think a spacer will help. They seemed to have room on my Norris SS and Crower SS rockers but only on mock up.

I have the HS 1.65 rockers, they rub the bolt hole groove on the valve cover. The second rocker from each end need to be rounded off a little to clear. There is plenty of room at the top for the polylocks and rockers. It is the big blocky pushrod ends that rub the valve covers. Wheelspin posted a good post last week on what you need to do.
