i got a new set of gaskets for the flathead im working on and it came with all the gaskets heads intake all the manifolds and water neck gaskets and etc even new water pump gaskets i was amazed from fel-pro from my local auto parts store and all of it was 45 .00 i thought was a good deal :) anyway it came with 8 rubber washers it says are the new intake seals . only thing is im replceing 4 valves in the motor and none of them was intake there are all exhaust so i do not need to use them right ?????
 
you are correct, sir....and that sounds like an excellent deal....what parts store??.....good luck....Mike
 
The intake guides have a grove in them for the rubber washers. I don;t use them, I coathe guide with a thin film of RTV.
 
Yep' I have used the red high temp RTV. Have had problem shearing off part of the washers when installing.
 
ok i read abot them and that was one my first thoughs i was like these has to go on the guide and then be put in the whole year tearing them up be first on the list :)
 
The only other glaringly obvious thing is that your engine may have been assembled using only exhaust guides,(all 16) meaning there would be no groove to put the seals in. (which is o.k. apparently)
 
OK, I'm going to tell you a little trick on putting on the guide seals without shearing them off. First get the seals from BEST gasket co. They are round not square on the edge. To install them on the guide, grind a little tapper around the top edge of the lifter, smear some lube on the top of the guide and they will pull over the guide easier. NOW make sure the guide hole is real clean. Smear some lube in the guide hole and on the guide and seal, install the asemably in the hole and with the back palm of your hand tunk the head of the valve and it will snap right in the block where it belongs without shearing.

so u could use all exhaust guides in a motor . i was told the other day u can use either exhaust valves or intake valves in either hole of the motor . cause i have some bad valves and only ones i have was ones out of a 8ba but there dished in the middle and was told i could use them as exhaust valves even thow in the 8ba they was intake . its cool u can changed things around .
 
We aretalking about guids, not valves. Do not use intake valves in the exhaust.
Now as for the RTV I use the Blue or black or the white because I'm lazy.
 
i understand that ol-ron but when a place like h&h flathead and van pelts say u can use a intake valve in a exhaust hole that it dont make a diff im going to trust there saying after all they build flatheads every day and dump thousands of dollars in there engines .
 
Check your valves with a magnet on the heads. If the magnet won't stick then they should work as an exhaust valve. If is does stick well then they should not be used for exhaust. Many of the new valves are all stainless which adds other problems to the mix.

Exhaust guides are not common now days. Most all of late manufacture parts have the groove cut in there to make them interchangeable. It also adds confusion about seal rings too.
 
I don't believe that is what they said. However when a company makes a valve it has to spend money to do it. IF the Intake and Exhaust valve were the same then they could save millions of dollars doing just that. The fact that they are different is because an exhaust valve is different to withstand the higher heat of the exhaust. This is logical, because it makes sense. BUT the guides are interchangable, but you can't put a seal on the exhaust guide when it's used in the intake so just put a thinfilm of RTV on it. UNfortunately nobody makes exhaust guides anymore. Just remember Flatheads were designed for the very wealthy and smart people. The SBC was designed for the mentally challenged and poor people.
 
idk like i said mine had 4 stuck valves in it and i needed 4 new guides as well . and they was all exhaust valves cause they was not the ones thats u can see doen the egg shaped intake hole on top of the block and i called van pelts in ohio and i explained to them what i needed even sent them a digital pic and the sales man said they was out of one of the valves and i told him and he said well the valves we have are intake or exhaust dont matter . what hole u put them in . i talked to this man for least a hour he was expaining stuff to me that i had the rotator type valves with short springs . so im going on what i was tols i mean this was van pelt sales soo . i take it they no what there doing . and as for using the rvt sealent around the guide mr ron i dont see that being a issue sence u gentleman say that the washers are a job to deal with i can understand that puting the sealer around the guide as a nice fix :) i just ordered from them what they told me i needed or would work and be ok .
 
You are probably all correct.
52 ford v8, obviously the latest valves are interchangeable, but when Henry made them they were not. This may or may not apply to standard valves pre the rotator valves.
Valves have been improved over the years to suit changing demands. One of those demands is probably to standardize stock lines. The result is probably that the inlet valves are now the same valve as the exhaust. Better quality and more expensive.
 
i tryed that trick today with the magnet and i see the differnce exhaust valves the magnet will not stick and the intake valves the magnet sticks to them awesome .
