My father and I are currently rebuilding an original 289 from a 1965 GT350. We are putting the heads back together and looking for information on a correct head gasket to use for this. Would aftermarket head gaskets be considered poor taste? IF not where could I source original head gaskets? IF aftermarket is ok what are some recommendations?
Also is there a correct painting of the valve covers? From what my father remembers the valve covers were black crinkle with the powered by ford and raised bits being unpainted aluminum. Is this correct?
Thank you for any assistance
Nick
For 1965 (and about the first 1/3 of 66) the correct valve covers are open letter and unpainted. They are sand cast and say Buddy Bar inside them

Later valve covers did black crinkle paint and were die cast with closed letters.

If I remember the HiPo used a thinner head gasket. .030 vs .040. Someone will have the correct part #. I'd use something modern unless this will be some concours trailer queen.
Hi Avogodro,
There are NOS head gaskets out there that might fit the desire, but I would not advise using them. Who knows how they have ben handled over the years and if they are still good. I'd go with a modern head gasket. I have had good luck with the FelPro Head Gaskets. It would not be any fun to put together with a NOS period gaskets and then have to redo because they did not work. A blown head gasket and coolant spewing all over you nice engine compartment would be awful. Just my thoughts.

For an engine like you have I use the Ford Racing "expanded graphite" head gasket , P/N M605i-C51. You DO NOT need the "special bolts they mention on the early 289 block. Once installed they look very close to originals and will not fail.

You mention "special" head bolts on early hipo engine. How do they differ than the "standard" bolts. Other than being "special"...

Standard 289 head bolts are normal "torque spec bolts. The "new" ones for sell with the gasket/bolt "kit" are torque to yield and have a "washer head" design like a Boss 302 head bolt. "I" refuse to use the torque to yield bolts.

+1!! TTY bolts suck!
Thank you for the replies.
I don't plan on this being a trailer queen. In fact we have been thinking of getting it to running condition and driving it as is for a bit. I think we would use a modern head gasket. We will be looking at the felpro and the Ford racing graphite gasket. Are all modern gaskets made to be right/left independent? We have another set that has a raised crush ring around them but the ring is block side down on the right and head side up on the left see the attached photo.
I would suggest ARP head bolts and know they're going to do the job.

You need to have the water jacket openings as you have them. Flipping a gasket to make the crush rings the same on both sides is almost 100% guaranteed engine failure. The ring itself doesn't really care if it's up or down once everything is torqued down.
Thank you for clearing up the crush ring question for me. It doesn't look right but it makes sense. Does anyone have a source for rocker arms and the corresponding nut? We need enough to finish off one head.
Thank you for all the help.

Pioneer Products still offers them. BTW ''factory" head bolts are grade 8 and have never failed me in the 54 years I have been building 289s. Nothing wrong with ARP except the extra cost and non stock looking bolt head.
A few more questions regarding the motor rebuild
1. Can anyone give me a good source piston rings and possibly a new piston as replacement for the original? Trying to avoid chinese parts.
2. How can I prep the valve covers? Should they be bare aluminum or painted/prepped somehow?
3. Is there a specific color black to paint the block?
Thanks Again for all the help.
Cant wait to get this car going.
If you have the 289 HiPo from a '65 GT350, please contact Howard Pardee, the SAAC Registrar, and share the Ford VIN stamped on the block. Your engine would be extremely desireable to the current owner of the car it belongs to...certainly enough to purchase another 289 HiPo engine and then some!
We have the car it belongs too as well... 8)
1. I would replace any stock pistons with a quality forged piston, new pins and plasma moly ring set. Call these folks and tell them what you want for a finished product. Are you planning to use pump gas? If so you will want to lower compression to less than 10:1. You don't want to use race gas all the time do you? Stock compression is too high for pump gas. http://www.raceeng.com/
2. No paint. BARE ALUMINUM!!!!!!!!
3. Gloss black. Any good brand will do. PPG, Sikkens, Akzo Nobel - you use what your normally would.

Right, bare aluminum assuming that these are the sand cast "open letter" covers. Which they should be as you have a '65. The so call "solid letter" die-cast covers were painted "wrinkle" black which is typical of the covers from the change over in 1966 and through the end of production in 1969.

When it comes to pistons talk to the piston Guru, Randy AKA gt350hr as he has been in the piston business for many years.

Thanks Roy , I have sent a PM to the OP and will help him out. 30+ years in the custom piston piston industry pays off sometimes.
