Hi, Everyone! I have a '71 Mav with a 200 (no ac, no power steering or brakes). Having drained the radiator to get a leak fixed, I decided to get the valves serviced, replace the clickety valve lifters, check the pushrods, etc. I came upon a video that showed the use of studs instead of using bolts. What are the thoughts out there about using studs? Also, I'm considering replacing the exhaust manifold because I'm afraid of snapping the bolt holes in this 52-year old piece of iron. With the head off, I'll also be replacing the ex-manifold studs--or have the machine shop do it. Is there a recommendation for a made-in-America ex-manifold, or is that as rare as a unicorn? Thanks all! (I'll also change out the timing gears and chain. Who do you recommend?)
Head studs are usually an improvement over head bolts. Better clamping force and easier to get the torque values right. They can get tricky on a V8 in some cars because they complicate taking the head off while the motor is in some cars, but on an I6, where you lift the head straight up there should be no issue in a Maverick. Not sure about the exhaust manifold, or what you are asking. If you need to replace yours, another member here likely has one. Pretty sure some older Mustangs and Falcons had this motor, so they should be common enough. I would probably have a machine shop make sure the mating surfaces on the head and manifold are flat, maybe do a light clean up pass on them.
NICE ! Early Maverick base model with a 200 is simple honest car with rep' for easy repairs or upgrades. Auto or Stick ? Replacement OEM Exh. manifolds available from many vendors , fancier tube Headers are also available for a price upgrade inspecting/replacing 'valve job' accessible parts like lifters and timing set is a good idea while head is off. 'valve job' upgrades can include back-cut valves, SBF V8 valve springs and modern valve guide seals . Head Studs are good idea if head is frequently R&R'd . OEM head bolts are fine for mild performance and ARP bolts are recommended for serious compression or forced induction. plenty more info on optimizing performance of the Ford Small Block Six over at : https://fordsix.com/ manifold https://www.falconparts.com/ford-falcon-auto-parts/pc/EXHAUSTS-c66.htm https://www.ebay.com/itm/166010910272?hash=item26a7057640:g:Eu8AAOSwSDJkKKFf&amdata=enc:AQAIAAAA4LAw6iOUs1VIDwjJV7BfvZSzcrE1K7U7XnkjDCImm70SEpeCjJmu6xDI3eeyDwzEF3YTaIf7kRD6H2sqf3ixjvZlIPJse9FZpqVG+T+QRTFVAEU9yzjrZ0GPFHTATk9jX/W0In99N0rEPSTWZYfzak6CsjHi8uPTB4FOm1Uv4Fq2fh089Y2/JXr84VK0ujEid9IYjbs7jLjtZapgNg5r17DUTKXOPKbonk+2kwBjsn4bm4PkqKjj0g7FRDgI4Sdn1vjGQH4lEPOZnBPvHveCwT5zgVfABJxLyamrWr3jfHkJ|tkp:Bk9SR5ztzOX1YQ Ford Small Block Six 250 CID inline .
