Stock is about 1.2 bar or 17.4 psi so you should be ok with .030" gap

I didn't realize it was that high stock. I want to get a couple years out of it before I start getting to crazy. You've helped me more than you know just from looking at your builds so thank you

Woah, wait. I'm allowed to not read your journal for months but you're not allowed to skip one single bolt.

Work looks great. Please catch us up.

Alright, going to try to get this train (journal) rolling again. *cracks open beer*

Here are the Mahle strokers pistons going back in.



Pins and clips properly installed



ARP head studs installed. Should have really gone with ARP case/main bolts too but my budget was already tight

Up next were the heads. I didn't anticipate doing all the work that I did prior to starting the rebuild. The original plan was to clean up the valve heads and replace the guide seals. Mild port job, valve/seat lap, oil drain-back ports smoothed, measure and re-shim every valve were eventually added to the list.

camshafts and some buckets and shims removed



all the buckets and shims gone



springs, retainers, keepers and valves gone. Still need to replace guide seals.



Organization is key. Please excuse the orientation; photobucket is retarded. I rotated in the pic in photobucket but since its retarded, it still isn't orientated correctly.



new guide seals from 02-05 USDM WRX gasket kit vs old, original v5 STi seals



Everybody loves port work. This is far from spectacular but anything is better than stock; and stock EJ207 ports are pretty big The pictures below aren't what the final result actually looks like. Unfortunately, my photo-documentation skills need some refining.

before pic



gasket matched. left vs right (stock)




cleaned up the casting marks and worked the long radius (I think that's what its called).



I did get a little more wild than what's shown below





Didn't get "after" pics but I cleaned up this nastiness



time to clean up them valve seats



much better





before and after cleaning up the valves



When I was lapping the valves, I figured the camlobe to bucket clearance would tighten a little but still be within spec. WRONG. Guess I got a little aggressive. Had to order some new shims straight from Japan; what a PITA. Luckily, I was able to reuse some of the existing shims.
