Hit a snag in my build..need help asap
 

Just got word from the engine builder that my stock 525 sc valve covers...the blue aluminum ones will not fit on the dart iron eagle heads I have...They said the gasket surface on the valve covers doesn't line up to the head sealing surface...

What are the least expensive options I have here?? this is about the last piece of the puzzle and don't want to spend hundreds of dollars on valve covers if I don't have to....

thanks

never heard that one before.... I have heard height problems, drip nib interference etc, but never the base being different...

Call Dart?? they should know what fits if their heads are odd shaped

Run a regular gasket with a steel core on the head and keep the O ring gasket in the valve covers and put it on top of the other gasket.
Something like this https://www.summitracing.com/parts/f...make/chevrolet

So basically just stack the gaskets?? Have you tried this?? I'm only asking so I don't spend the money on these gaskets to have it not work...I guess I could use the gaskets regardless on new covers if it doesn't work

Man, not to rain on your parade, but if your building a blower motor and stressing over the cost of valve cover gaskets, life is going to get ugly.

I'm not stressing about it but would like to avoid unnecessary cost wherever possible...thanks for your input tho

Thanks Jay...I'll get them coming

This works, many have done this for years.

sounds good thanks!!

i hear ya... If I had a nickel for everyday unnecessary dollar I have spent on my resin bucket, I could buy another resin bucket and be even further in the hole....

I'm so confused on gens at this point lol...it does not have the fuel pump provision...its has the pump on the water pump and it did not have the cam retainer plate..has the button on the cam...the heads are already assembled and on unfortunately...the valve cover gaskets were the last piece of the puzzle besides smoke checking the engine to look for leaks

BBY, that is a gen 6.........Im pretty sure my Edelbrock 525 heads are 3/8 on one end and 7/16 on the other.....leave it to Mercury for the 1 off head design.

haha yea figures...guess I'll have to buy some bolts :bsflag:

Does it have an aluminum timing cover with 6 bolts? If so, it is a gen 6. If it has a cover with 10 bolts, it is a gen 5. If it is in fact a gen 6, I would advise against running a cam button on the aluminum timing cover. The retainer plate is a much better and safer setup.

Correct ^^^ run a step nose cam

You have to machine the drip rail down to the same level as the stoppers on the outside of the bolt holes... at that point they'll drop on and seal like any other cover... been there done this got hat and T shirt

I believe it is the 10 bolt cover...I brought up to them about using the retainer plate and they said this will work just fine with the button...I'm just taking their word for it at this point I guess...hopefully it holds together!! hahaha
