I'm gonna replace my head gaskets but my budget is a little tight, so what would be best for the money. I've seen them as low a fifteen bucks each to forty and much more. Unfortunenatly there's not detail on the different gaskets.

Fel Pro 9333-PT-1 will do the job well. About $20 each and available almost anywhere.

Yeah, I've always been a Fel-Pro fan. I saw some Fel-Pro gaskets around $15 then $20, $40, and $100. I'm just womderin' about the differenc 'tween the cheaper ones and how they would hold up over time. I don't remember what I put on back twentuy years ago when I built the engine. I'm runnin over 10:1 compression yet I hope that I don't have to fork out $200 for some gaskets, but I will if I absolutely must.

pick any non-MLS felpro
cheaper felpro 8240 (I guess) than 9333 is OK too, IMO even better for non-machined blocks/heads because it has milder steel rings (rest is identical)

I really didn't thin it would make much of a difference, but I thought I'd ask just because technologys has improved over the years.

If you are going to reuse your head bolts make sure to put them back in the exact hole they came out of.

Re-use of head bolts should be avoided if at all possible, due to stretching at specified torque. If you have to do it, do as Rusty said and make sure all threads are clean and re-use only for the lowest of performance (compression) applications. As with any torque dependent fastener, make sure to lubricate the threads and underside of the bolt heads to achieve maximum clamping force for the given torque. With a small block Ford, on the lower head bolts that need thread sealant, the sealant (while still wet) adequately doubles as the lube. "A lubricated threaded fastener will provide up to 17 times more clamping force than a dry threaded fastener!"
My $.02,

not all small blocks have stretching bolts. e.g. older 302s have regular bolts (reusable in any hole). if you have strechning bolts do not reuse them.

67rcks you shouldn't reuse them in different holes. ARP put out a white paper on this after an extensive study. I don't have a link to it but I'm sure I can scare it up.

regarding which gasket to use, in my opinion felpros are the best, or at least very near the top.

in regards to the head bolts, stock 302 head bolts dont stretch much, and are not torque to yield bolts, however chances are that they are original equipment and are tired. do yourself a big favor a pony up the few extra bucks and get a set of ARP head bolts for your ride. and dont forget the ARP lube that goes with the bolts.

horseball (maybe others) which small blocks do need sealant on lower head bolts?
I saw 302 and the threaded hole did not protrude to cooling system, why would you then seal the threads?

to be honest i have never put sealant on any head bolts, even a small block chevy where i knew the heads bolt holes went into the cooling jacket, and i have never had a leak. the key is to keep the bolt holes and bolts clean, and torque them properly.

it is also a good idea to run a tap down the bolt holes to clean out any rust or carbon build up ,you can tape off the cylinders to keep crud out when chasing the threads
dont break off the tap been there done that ,wont do it again

Agreed. I never used sealant on any either. The 69 ford shop manual, and my Haynes manual do not state any sealant either, just oil.

I did however use new arp bolts any time I pulled them off, and the fel pro gaskets with the pre-flattened copper ring around the cylinder opening.

the copper ring works nice, but i tend to prefer the steel fire ring instead. just a preference though.
