Copper head gasket or best Kevlar? Am I correct in thinking that the Model A engine was built using copper head gaskets? I never had much luck with copper on a couple V8 Ford engines so I thought I would go with the Best gasket that Brattons sells,Kevlar and graphite. Anyone successfully use this gasket? I am having second thoughts because of a post from an experienced engine rebuilder who uses only copper.Brattons sells a Felpro copper gasket but only says it has a gray material in the middle not what kind.A better copper gasket available preferably USA?

Re: Copper head gasket or best Kevlar? Back in the '50s I did a LOT of work on flathead V8s, the available head gaskets were either copper clad or steel clad. We always used the copper clad ones with no sealer and never had a problem. You have to be sure that both the head and the block are perfectly clean and that the gasket is installed w/the proper side up.

Re: Copper head gasket or best Kevlar? More info on the Ford Garage.
Home page http://www.fordgarage.com/ Head Gasket info http://www.fordgarage.com/pages/ABcy...asketguide.htm Do not see info on a solid copper gasket. Has info on what was originally used. |
Re: Copper head gasket or best Kevlar? I prefer copper as they are easier to remove and can often be re-used. I've never had a problem with them sealing. Best makes their #509 in copper or some kind of material that works well but is a pain to scrape off when changing heads.

Re: Copper head gasket or best Kevlar? The Secrets of Speed Society recommends the Best Graphtite gaskets with no sealant. I have never had a problem with these gaskets either with Y-Blocks or Model As. They recommend 55 ft lbs max.

Re: Copper head gasket or best Kevlar? Whichever Best gasket you use,they reccomend copper coat spray. I use the grapftite on my A and Flathead.

Re: Copper head gasket or best Kevlar? Back when Brumfield was making heads he would not honor warranty if any head gasket was used other than the Copper FelPro 7013.

Re: Copper head gasket or best Kevlar? I recently installed a Best brand kevlar (they call it graphite) head gasket on a Model A. I followed all directions exactly. No water seepage, however when pulling a hill in 3rd gear at 45 MPH or so, the combustion gasses are getting into coolant and blowing the water out the radiator overflow.
Yes, I have re-torqued it (read above where I followed ALL directions). The block/head are flat. Going back to copper gaskets. No problem with those. |

Re: Copper head gasket or best Kevlar? Could also do radiator exhaust test yourself. $45 dollar Napa Block test kit.
Radiator issue? -How old is it? - Has it been flushed and back flushed recently? - Empty it, block the upper and lower openings, should hold 1 1/2 gallons. - Could be partially plugged or if old fins not making good contact with tubes. - How old is the radiator, fins/inch, rows ?. - When run and and stop/turn off, does it burp coolant? (running hot?) |

Re: Copper head gasket or best Kevlar? I know you guys are just trying to be helpful, and I thank you.
However, I am most positive that it is combistion gases blowing into the coolant. No question. That is fact. Otherwise, I wouldn't have said it. Fordbarn forum can be a blessing and a curse at the same time. Someone comes on here and says their steering is loose and there is always someone quick to tell them their timing is off. |
Re: Copper head gasket or best Kevlar? We produce a copper one that is sealed around outside edge so no weeping down the block , can also be used on B engines too . Wet & cold in NZ plus 6.7 earth quake few mins ago.
