I'm baffled....lol (valve cover q)

Hey again!

Oh man this weekend sucked. I am like two seconds away from starting my motor but I don't have the appropriately tall valve covers! Oh and BTW for anybody reading, if you swap from an edelbrock manifold to a weiand, your alternator bracket is now useless! So I'll need one of them's too.

Anywho, I have to order up a set of tall valve covers to clear my rockers (thought my old ones were?!) and most come with the option of being "baffled" or "non-baffled." I assume this talks about the little metal box welded in under the PCV valve to limit oil consumption, so why would anybody want a non-baffled set?! What are the disadvantages to having a baffle, and the advantages to having your VC non baffled?

Just checkin before I place the order-

K

Non baffled tend to load the pcv with oil.

A non baffeld set is good for someone not using a pcv valve,and is required if you are using a stud girdle or shaft mounted rockers.Most racing valve covers come with no baffle and no holes in the covers which is good because you can drill a hole and put your breather anywhere you want.The is a bonus for street rod guys too since they can tuck their pcv valves in a hidden location such as the valley of the manifold and run smooth top covers.If you think you covers are tall,but they still dont fit,try running 2 thick gaskets by laminating the 2 gaskets together on a bench using weatherstrip adheasive{3M snot glue},and then snot glue them to the valve covers.If you are using tin valve covers,dont ighten them too much,just snug should be fine.Many aftermarket rockers will hit the covers on the inside wall of the cover,not the roof,so you may need to be careful when tightening the covers to make sure that if there is any potenial movement when tightening,that you make the movement in favor of giving you more clearnace.Good luck.
BTW,if your alternator bracket problem pertains to the water neck bolt hole,you can fix that by cuting off that part of the bracket and it will often work.If it doesnt,then try running the cut top bracket and also removing the metal spacer that goes to the cylinder head on the lower bolt and just running the lower bracket with a short bolt.That trick always works.Good luck.

The baffles will hit the larger size rockers.
If you need a taller gasket use a Fel-Pro # 1604 it's 3/8" thick.

... I'm a goof. I think I just had a tight fit getting the cover in, I tried it on the other side, clayed it, and it looks like I've got space!? Well in any event, I still need that alternator bracket-

If you have a long water pump, get Summit's billet aluminum bracket #SME-2000. I have one an it works good, especially for only $60. It mounts the alternator on the passenger side. You can see it here in the left picture - http://www.edgesz28.com/edgesz28/cooling.htm

For the short water pump, they offer two versions, high mount #SME-2001 and low mount #SME-2005. But these are DRIVER'S side and run $70. Good luck, Ed. www.edgesz28.com
