Work killed me, so little delay but got the coil harness out today, should see em on Friday.
As far as deck RA, what type of HG are you planning? I know cometic are particular with what RA they call for. I would get em checked or borrow a surface check.
Awesome, what do I owe ya?
Hopefully the 24x and head stuff will be over with by the time I get the shortblock back. Karl is scooping up the rotating assembly tomorrow from the balance shop. He's also gonna check with the main cap guy to see if the block is ready and possibly grab that too.
Yeah, this machine shop blows. Hopefully they'll own up to how they enlarged the guides on my heads way too much and do something about it or at least reimburse me for work elsewhere. I'm pretty pissed but will try to refrain from arguing with anyone. Hostility isn't going to do me any favors right now.
I think the machinist only honed the intake guides by looking at my measurements. They're all in the .0020-30 clearance range whereas the exhaust guides are all around .0014-.0016. I did some swapping with the exhaust valves to get everything as close as possible. I figured it wouldn't matter with a fresh valve job on heads that were never ran.
Not sure what RA AFR mills their heads to, but there's a pretty big disparity between the deck and intake/exhaust sealing surfaces. I'm assuming AFR mills those surfaces to the same RA as the deck (if not worse RA), but this fresh mill job feels like a nail file compared to it.
Head gasket should be Felpro 1074. edit: not MLS. Karl recommended finding another shop... he's definitely right about that.
If I remember correctly, the FelPro MLS needs a much smoother surface vs Cometic. The Cometic has that black coating on them that makes it good to about 80 RA where as some other MLS gaskets needs it to be in the 20-30 range.
Better check with a competent machine shop and/or gasket manufacturer.
I took them back to the shop today... didn't have to argue with anyone. Hopefully they'll make things right.
If they press out the guides and press in new ones will a valve job be necessary to seal? Just a thought.
I run a 1074 and I don't think it's mls. Mine have held lots of abuse.
I think you're right, I'm reading stainless steel wire laminate w/wire rings. I forget where I saw MLS. Trying to get a hold of a FM tech to get the right RA spec.
The recommended gasket for the AFR 210s is the 1074.
edit: The spec from Felpro for those gaskets is 50-60 RA. How smooth was my local shop's mill job? No clue :shrug:
You are a mechE student no? Go find a M&M lab, borrow a surface profilometer. :lol:
Are you assembling this motor or a shop ?
I'll stuff the AFRs in my backpack, no one will notice.
Karl is doing the shortblock and degree-ing the cam but I'll be assembling everything beyond that.
Everything I need to have done before I get the shortblock...
Harness repin
Fuel rail fab (I can drill bores but will need someone to tig AN ends on)
Fuel rail mounts
Route fuel lines and mount FPR
Mount MAP on intake
Drill and tap for MAP/FPR/PCV barbs
Clean heads, lap valves, and assemble when they're fixed
CC chambers and adjust if necessary
Make 17* angle washers (finally got the right saw blade to cut up the stock)
Pick an oil pan and have fittings welded on for blower return
Figure out what I'm doing for PCV system
After I get the shortblock...
Check PTV
Bolt heads on
Measure pushrod length and order correct size (doubt I'll be able to use Comps from old setup)
Assemble valvetrain
Check intake port alignment (looks close)
Drop engine in car
Mount intake
Figure out exhaust ??? Hope I can clamp my Pacesetter ORY and Magnaflow on for the time being
Reassemble everything
@GuillaumeC
Do you plan on selling those 80lb Dekas any time soon?
