243 heads for my ls1 or intake

I'm doing little research and wanted to ask you guys and girls opinions on what to do.
Truck is currently cam only with bolt ons
Assume stock ls1 heads 00 c5 is on the truck.(853)
I'm wanting to find some 243 heads and have them ported as well.*
When buying the heads what do I need to look for to tell if there in good shape?
Where do you all recommend as far as a machine shop?
And motor currently has stock truck intake. Can I have that ported?*
If I buy intake I would like edlebrock high rise I know there best for boosted apps. With that said I would have to change the tb to 4 bolt 90mm. And fuel rails
But if performance is better I would consider ls6 or fass. But I would have change my front accessories currently ran with truck set up.

Any tips or advice be appreciated

I basically have enough funds do either heads or intake route

 

Tough choice. Yes your intake can be ported. I talked to a tech at TSP about getting 243 heads and port and polishing them and he said if I'm going the machined route, I might as well just machine my stock heads rather than waste money on buying different heads, and then spending money to machine them. He said I would basically see the same gains... As far as an intake, I don't have much personal experience, other then the tons of research ive done myself. The guy at TSP is the one who told me to port my stock intake as well. If you're looking for something new though, the FAST LSX-R is awesome. Be ready to drop about $1,200 though.

 

I would do heads over intake if those are your options. The heads will give you the better gain.

 

do both. i would just mill some 243 depending on ur cam specs and get a tbss intake and tb..u will pick plenty and have a grand in the whole setup..imo
