Hey all,
I have recently finished my motor in my xe and had some money aside for a respray and maybe some wheels, but also looking for a new set of heads instead of spending anymore money on these current 2v irons...
I guess i wasted a bit of money on these 2v closed if i get rid of em but I dont see putting any more into these as being smart, spec with postage on the fukas back and forth! I have spent about $1000 on them with cleaning and harden seats etc...

-now I have found a bare pair of AFD 2v's pretty cheap , which i am going to jump on. I am wondering if i can wack these on and retain anything off my iron 2v's.
-I have only standard valves so they are goin...
-i brought a small crow value train kit K2102 for hyd's...
-crow hyd cam 21665.
Can i run the AFD's with any of this, as its taken most of the left ova budgetfor the AFD's i dont wanna sit there looking at them really :(
I will def go mech cam, but i dont have the $$ upfront atm..
Can i run the bolt on rockers on machined heads?
-or if i do have to get adjustable rockers, can i leave the hyd cam in for now? or is it just worth replacing it while the heads are off?
I am not sure what combustion they are, either 57 or 64 so...
As i have posted with some pics i have pretty big dished pistons which had me at 10:1 with 2v closed. what can i expect with AFD's?
will this match my combo basically?
bloody sorry this is long, lots of stuff going through my head..
AFD pretty big investment :)

also are normal radiators sefficent? or do you neeed alloy?

thankyou!

Don't run a small can if you go the 57cc version. Although the alloy is great in regards to combustion control.

You have to buy screw in studs and stud mount roller rockers. Which are adjustable anyway. Yes, you can run your springs etc. Just make sure you run spring saddles (spring pads) so the springs don't eat into the alloy. Stock clevo head bolts due to the large head on them do not hurt the alloy.

Normal copper radiators are fine. Just run the correct coolant for the alloy and your in business.

Just remember to oil every bolt etc before tightening. Nothing worse that fusing things together due to friction. Also aids in removal if required.

thankyou for reply brenx!

do you think these heads will suit what I have?
can i run the adjustable rockers on my hyd cam for a while?

brenx

Yes, you can run the adjustable ones on the hyd cam. You just adjust for zero lash.

I forgot about the dished pistons. Silly me! The 57cc version may suit but you'd have to work it all out. I can guarantee they'll be better than the cast irons I have no doubts there. Alloy has too many positives not to use it. The abilility to run higher compression does wonders. Which I am sure you'll find.

This is what I'd do if I was you? I wouldn't fit the heads without the larger cammed complete setup. As this way everything will match. No sense building it to suit a small cammed setup. You'd still see benefits either way. I know it'll kill you and you'll be itching to have it going but in the long run it'll make your life easier.

I tend to plan for later down the track not what I have now.

yeah I am looking long term, but it wont cost be much to wack the alloy on for a little while either so i was just asking if its work with hyd.
can you pls have a look at www.crowcams.com and tell me if the pushrods etc are def ok to use? Kit K2102
VALVE SPRING- 7738
SPRING RETAINER- 127008
VALVE COLLETS- 117028
VALVE SEALS- HR229
PUSH RODS- PR-4146

Valves - need upgrading anyway

anything else i will need to change other than mech cam and lifters?
also do u mean they are ok to use with only the hyd cam? or can i just buy new cam and lifters and use my old value train?

what size combustion is closed 2v's?
I run at about 10:1 with the 2v's and dished pistons...
can someone pls giv me ball park with 57cc AFD's CR?
I am guess it will either stay about the same or go a lil higher CR? but then i hear alloys handle high CR easy, so if its does lift CR to maybe around 10.5:1, it will still feel lower CR and need a bigg-ish cam?

I only really have about 2 days max to decide to buy these so I am lost a lil!

whats a good! price on a bare alloy 2v's?
