Considering a few engine mods. Opinions?
Considering doing a few slight mods over what I have now:
stock cammed 86E with ported plenum, 52mm TB, TPIS base, 42# injectors, 1.6 tappet rockers, Vortech V-2 SQ @ 10psi, alky injection, 2.59 gears, and full exhaust (ceramic TPIS LT, gutted cat, SLP muffs, new rear Y-pipe).
Upgrades I'm considering:
Edelbrock hi-flo runners (are these worth the $ for an FI appication)
full roller 1.6 rockers (benefit over the tappets worth $200?)
blower cam 224/234 @ .050, .465/.488 (.496/.520 w/1.6's) 114 LSA
3.07 gear install (have them already, just collecting dust)
I think I'm losing a lifter on cylinder 7, so I'm pulling the intake anyway, just wanted opinions on the benefits of these mods while I'm at it...
Thanks in advance!

In you comment full exhaust I hope you meant LongTube headers (I used MELROSE), and if you area permits no cats, egr,and AIR all easy fix and won't hurt since you will have to have the ECMchip burnt (HIGHLY RECOMMEND PCMforLESS aka:Alvin)
.Also go with roller lifters since the 86' did not come with them. Sounds like you are off to a good start. And like alot of the guys/gals say around here RACE ON!

I would definitely do the RR and camshaft. If you can port the edelbrocks yourself, then I dont see any reason not to do it.
Gear change would be expensive for little improvement, that would be the last one I'd do right now.

After reading up on both post in tech and F/I, here are the changes I have come up with:
Lunati 50155 solid roller tappet blower cam at 215/218 @ .050, .489/.503 (.522/.536 @ 1.6) 115 LSA 110 centerline
Comp Cams hydraulic roller retrofit lifters
Crane Energizer 1.6 full rollers
World Products Sportsman II 72cc chamber 200cc intake runner 2.020/1.600
Edelbrock hi-flo runners* I still haven't decided if these will benefit me enough to drop the $ on them with this setup.
I have retrofit pushrods and such listed as well. I may go with a thicker intake gasket to try and maintain my CR (and try not to blow these cast pistion completely apart!), maybe a .043" compressed gasket?

That was the cam/lifter combo recommended by Lunati on their website, operating rpm is 1,500-5,500; about right for the TPI setup although I could still go with the hydraulic tappet and save a ton of $. I was slightly hesitant about using the hydraulic roller lifters as well on a solid roller cam. I would like a slightly lumpier idle, so I'm still checking grinds.
