i am using heads that require the EARLY style head gaskets on my later style block. i have read the searches and found these part numbers in relation to the BLUE fel-pro gaskets..the part numbers turned up these http://www.napaonline.com/cgi-bin/n...tail.d2w/report?prrfnbr=15515850&prmenbr=5806 are these right they look BLACK to me...are these the style that do NOT need any sealer?.. no one on any of the searches had any reviews of them really ( although that was a year ago) any updates? also i plugged the holes in the block that i needed to ....should i plug the coresponding water holes in the new heads or will the gasket that care of those since the block is plugged any advice appreciated.......
i think its a stock size that can be used to to a 3 5/16 bore here is the post that i had gotten the pasrt numbers off of... http://www.jalopyjournal.com/forum/showthread.php?t=22778&highlight=flathead+head+gasket i am still interested in peoples thoughts and experiences with this gasket i have a copper one waiting but if this type is the bee's knees then i would rather deal with these and eliminate ANY possibilty of ill effects from the copper style.....
I just got some a few months back - NGA1026K - when I got them, they were blue, but in a Victor package - I pulled them out & they were indeed Fel-Pro - they packaged them so you couldn't see the Fel-Pro name... NAPAOnline isn't always the most accurate - go order some at a store. If you're using early heads, there shouldn't be any holes to plug.
thanks Flat Ernie.. do i need to use any kinda sealant on these or do i just crush em when i torque em? it appeared to me that one of the holes in the pass side head did NOT line up as the corresponding hole in the block (8BA) stuck out past the head (which needs a plug) so the hole in the head just dead ends into the gasket thats why i was wondering ...similar story of the drivers side.. thanks again
Shouldn't need any sealant & despite Fel-Pro's no-retorque claims, I'd check 'em a few times during the first 100 miles or so. If you've got early heads & early gasket, just plug that hole in the block & you're good to go.
The NAPA site is unclear and incomplete; I just ordered a gasket set and also a spare set of headgaskets (because I couldn't tell what type of gaskets came in the engine set). I believe all the gaskets that came were the blue new type, which get good reports from the only person I know who has used them. We were looong overdue for new gaskets, especially for engines with aluminum heads... By the way, virtually all applications needing early head gaskets should use the small-hole type--even early trapezoid hole blocks, all except thase using actual '39-42 Ford heads. The trapezoid blocks get minor redrilling detailed in Ford books to use the '42-48 type gaskets, which are designed for better flow through end cylinders.
I'm running them with iron heads (for now) & will get another set when I get my Cyclone heads on. I did re-torque after the first full warm-up & most of them moved a wee bit. I tried another re-torque after a few more miles & none moved. Which book is this in, Bruce? Is it something I can do with the engine together & in the car? I'm still battling a small overheating demon - it's controllable, but next time I have the heads off, I'd like to try anything I can to help cool it off.

I've got the Canadian engine book here... Give me a moment to translate the measurements from "Walrus Whiskers" to inches... Early heads, from Canadian manual: Look at the vertical row of holes down the center of the head: Topmost gets drilled to 3/4", skip a hole, hole #3 close to center gets drilled to 3/4". Then use late gasket, the one with only round holes, no trapezoids. If holes are already 3/4, you have some kind of late heads or they're already modified. What block and head casting numbers do you have?
