Time for a rebuild

Well guys I'm starting to get some parts together for a rebuild. Unfortunatly due to my other plans (looking into buying a house before long) I've not got tons of money to spend so I'm not gonna be able to afford the AFR 165's that I want so I'm gonna have to make do with my stock GT40's for now. The stock engine rattles and smokes due to the previous owner not fixing a bad balancer and the car sitting for 2 years before I bought it. I'm just hoping to make between 260 and 285 rwhp and be able to run high 12's in the 1/4 N/A. I may also add a 100-150 shot of N2O later

Here's what I'm planning for my engine combo.
Crower 15511 cam (should arrive today)
Stock cobra 1.7 roller rockers
GT40 heads ( new valve seals and valve job if needed and some very light home porting by me)
87 forged piston shortblock (new rings and bearings)
Stock cobra intake ( cleaned and powdercoated satin black and if funds allow I'll get the lower ported by Tmoss)
1 5/8" unequal length shorty headers for a fox body (I've already eliminated the EGR)

I already have
Tweecer R/T
3.73 gears
O/R X pipe
Flowmasters
CAI

Here's what I need help on
which Headgaskets? (Fel-pro 1011-1? 1011-2?)
valve springs? ( I sent a PM to thumper on Corral about the cost of his valve springs but haven't heard back yet)
which Timing chain?

What do you guys think and is there anything else that I should add?

I have seen those 9333's listed at my local parts store but I haveen't seen them in Summit. All they have listed is the 1011-1's and 1011-2's. That's my reason for asking.

Thanks, Jarad

Thanks for the links I just didn't see them in the catalog when I was looking through last night.

The only thing I see about those gaskets is the compressed thickness is .047 would I not lose some compression with those compared to a gasket with
.038 thickness or would it be enough to matter?

Thanks, Wes

Any more suggestions or comments on my low buck combo?

I got some headers and some new ford racing lifters today. The cam also came in.
