What components would you use when rebuilding topend?

So the beater SVT is going to need, at least, a headgasket, but while I'm at it I'm going to do some other things to. Problem is, I don't know exactly what yet.

I know I'll need a new headgasket, valve stem seals, and timing belt, at the very least. I also know I'll need new head bolts.

Should I fork out the extra dough for ARP head studs? There's a chance I might use a 50 or 75 shot on the motor down the road.

What's the best timing belt? I've heard of several different aftermarket brands that are supposed to be 'better than OEM' but I don't know which is the best. Do I need to replace the timing belt tensioner also?

What should I go with as far as a head gasket? Stock thickness, or maybe bump the compression up a few tenths with a thinner one? Probably not if I'm going to go with nitrous...

If your getting in there for that much you may as well replace the pulley's and tensioner for the timign belt, i'd think your more likely to have a failure from them then the belt snapping. I just got mine done, the pulleys and tensioner are fairly cheap.

If your doing the work yourself, parts are cheap: timing belt, pulley, tensioner, water pump, serpentine belt and serpentine idler pulley, parts cost for all that was around $250. I'd think its worth doing that as preventative if your thinking about getting a "better then OEM timing belt" your weak links will be old pulleys.

Ah yes, forgot to mention that I do plan on doing pulleys, water pump, etc. Will do the timing belt tensioner while I'm in there. I was just thinking of things that I could do from a 'high performance' viewpoint- what parts are worth replacing with better than stock pieces. Like the head studs- worth it? What about the Cometic MLS headgaskets? I could get up to about 10.5:1 compression, it looks like.

ARP head studs would be a good upgrade, but some new stock head bolts should be fine with a 50 shot if you want to save money. The Ford headgasket would be best, and a Ford timing belt is fine as long as you change it again in 75k miles. You also need a new timing belt idler and tensioner. Valve cover gasket is optional (they're reusable unless it's ripped; just clean the oil off first), but I would get new valve cover bolts and grommets, since most of the grommets will be torn.

I would recommend new tappets, but this will seriously increase rebuild time. You have to measure your existing tappet clearance, measure each tappet's length, calculate the tappet length you actually need to bring clearance back within spec, and then purchase the tappets that are close enough to the size you need. If you measure your tappet clearances and they're all within spec, praise your preferred deity because it's a royal pain in the ass.

So here's a parts list I'm starting. Help me out if I'm forgetting anything.

headgasket- 42.99
head bolts- 16.99 for Fel-Pro-
intake manifold gaskets- 9.00
Felpro Valve Stem Seals- 40.00
water pump- duralast- 50.00
power steering pump- $95.00 (ps not working on the car)
timing belt- 60, Ford
idler pulley 27, Ford
timing belt tensioner, 65
idler tensioner, 13
serpentine belt- 42
new Taylor plug wires- 50

That's already over 500 dollars in parts...whoa.

While the head is off I'll probably take it to a machine shop and have them do all of the internal work on it, clean it, and maybe a 5 angle valve job? If that would even help the already very good SVT head.

Also, if I wind up needing rings and the bores are ok, where do I get those? Can't find them online.

I'd go with the ARP head studs.... they are WAY better than any other ones you'll find.

I WONT put a motor back together with headbolts.

You don't really need to change the water pump if it's working. It can be changed later without removing the timing belt I believe.

Okay so if I drop the water pump off of that list and get a used PS pump from somebody on here I can probably add up to around 500 for parts even using head studs. Anything I'm missing on the list?

you'll be better off just buying the whole upper gasket kit from felpro, autozone stocks it for about 130$ comes with everything including the head gasket and the stem seals, I would relap the valves as long as you are doing the stem seals. doesn't hurt to make sure your valves seat right.
Also as for the rings you can buy a set of file to fit ones from autozone as well pretty cheap
