i have been in the middle of a head gasket swap for a couple weeks due to money and parts probs but i just got a lil padding back in the acount so...
i have my head off and its going to be decked and hot tanked... if i do head work what do you think i should get done... prolly a valve grind, port polish? im by no means loaded so i would like it cheap but im not settling for shitty( i know good head work isnt cheap but i mean afordable). i would also like some info on Nitro. bc i have the option to get a dry system really cheap and i wonder how harmful it would be? i know dry is alot safer than wet which is why i would go that rt.
any info would help i've been reading but thats never enough.

info on my car,
this is kinda Redundant but i have a
Hallman MBC,
ARP head Studs
MLS head Gasket (so compression should be at 8-1)
Upper Strut mount
Coil overs,
intake,
strait exhoust until i get it moving again
HKS FCD
i run Synthetic High RPM oil
NGK plat Plugs and wires
and i woul love the lexus afm
and walbro Pump and injecters.

it would be a 100 shot, i wanted 50 but i was told that 50 wouldnt do much good.

They don't hot tank aluminum heads. They glass bead them clean.

Have the head milled ONLY enough to true it up. They could 'back cut' the valves, for better air flow. But, I don't know that you'd gain much tho.

Thank you. and also before i get FLAMED dry systems in turbo cars are more harmful than wet i have learned that, so what about a wet system...or should i just build the car and not the bottle. if so what is the next step?thanks for helpin

if you mean they dont hot tank them b/c you think they will warp that is false, alot of people think that but if it is done right there is no damage at all.

the shop that is doing my work is wakeman auto parts they are cleaning and resurfacing my head new valve guids and poss. springs and valves.
if you people dont know about wakeman they do all of busher racing's engine work.

(john shepard) and fast ass DSM's
i pulled up and there where about 8 EVO's 5 Talons and 2 Brand New eclipse's which i was told now run 10's and dave busher drives one of his evo's every day and it runs 9's... must be nice... when i go back on wed. i'll post some pics. they also have a Evo that holds the fastes Time attack record in USA.. so at least i know the work will be done right. he told me he had built a bottom end for a supra and new crankshaft and the guy never paid or picked it up so if im lucky i will have a new bottom end lol..

and i'm not going to use N2o but thank's for help.....
