Before pics, I'm still going to get the machine shop to clean all the carbon out. I am aslo going to have them do a valve job with new 918 springs and seals. These heads are going to go on a mid boost set up 10-14 psi. I was going to put them on stock but just couldn't resist.



Now the after pics, I didn't want any real big changes I just wanted to clean them up a little, I have done a set of 241 heads before for a N/A project in the past.



Its hard to see but I took the hump out in the intake port, and I'm still going to polish up the exhaust port. So what do you guys think?

Did you do this yourself ? Nice.

Yeah this is the 3rd set I've done. I read up quite a bit on doing this before I did my first set.

Where did you get your info? I want to practice on a cracked 853 I have.

Looks pretty good. No chatter marks. If you are planning on that much boost I probably wouldn't run 918s.

No chater marks after my second cut with a smaller less aggresive bit!!! I rought cut the entire head and then went over it a second time to clean up the cut marks. You think I should go with patriot gold dual springs? I'm going to go 346 forged pistons and maybe rods, with a pair of 57mm twins. I know they sound kinda small but I want low rpm boost!!!

I have no personal experience, but I've seen some people have problems running 918s with boost. It also depends on how aggresive your cam is.
