Straightforward and easy to understand, great vid. Would be interested to see how you polish cams after they've had contaminated oil run through. Also would be interested to hear your take on deck surface finish, does the head need to be milled every time it is serviced to get a fresh surface?
What is the style/model of reamer you're using? A lot of reamers I see for sale online look much shorter. I'm looking to enlarge my 5/16" valve guides to 11/32" on small block mopar magnum heads. thanks
@@REPerformanceUK Thanks for the kind words! Great question! Because it's so much faster and more repeatable to get the correct reamer vs honing. We do still hone a few things but for the most part we ream all of our most common.
Hello, over the winter i eanted to port my supercharger 1G-fe engine. It comes na stock, is there anything to look for when porting an cylinder gead with a "fuel econmic" design that is turned into a performance engine. Is there any way to know that i wont hit any cooling channels ?
I would just leave it alone unless your making some real power with it. 800+whp then worry about porting it. We have never done a 1G-FE to know dimensions on how big to make it. If you hear it an echo stop!
this channel is becoming, very quickly, one of my favorite channels for head work
4:40 I'm freaking out! This is such a great video!

dude! Thanks for the feedback and the vid ideas!
I've always been told size is a personal preference for my reamer size too.
haha I'm learning the importance of proper valve guide clearancing the hard way. Thanks for this video!
Sorry to hear that! Hopefully this helps
Excellent video. I'm about to tackle the same job for the first time on a Ford/International 7.3 IDI diesel. Thanks
Very interesting stuff. Thank you for your videos.
Do you hone after reaming ? I’ve heard the finish is ready to run after reaming, others say the hone holds oil…but will polish out over time…thanks
we just ream, no need to hone it unless it is not to size.
Most excellent video thank you
thanks!
Would be nice to know clearance used in that application
.001-.0012
0000 thanks I live for the little detail thanks man great vid

hit up Dakota Parts Warehouse. They are not cheap. And that is a big jump.
i like the loose joke 🤣 great video thank you!
Thanks for watching!
Interesting videos. Any experience with Subaru FB16 engines? Am planning to rebuild one NA for 200 whp
Never even heard of that engine. So that’s a no
The FB engines are Subaru newest engines. So they have FB16, FB20, and FB25
@@headgames The FB blocks are more economic for fuel efficiency etc so they are very slow compared to the EJ and FA series
@@headgames The setup is basically the same as other Subaru engine models. They are the same boxer type engines
Perfectly acceptable. We´re not going to the moon.
Good thing no one's been there.
So, does the valve to guide clearance change with the type of environment its going to be used in?
Great question! Yes, but only a few tenths of a thousandths
Hello Dave, why do you ream your guides over honing? Love the vids mate!

@@headgames Does valve clearance adjustment add to horsepower?
@@prophet6896 I have heard people say that but I don’t think it’s true. A couple of thousandths of an inch is not enough to sway your whp.

You guys sell valve guide reamers for the 4G63 ?
How is guide-to-seat concentricity?
Perfect! No issues ever
Obviously you have to valve job it.
Thanks man.
thank you!
If I call Dakota, they can hook me up with any size reem?
Yes!
Thanks for the tip! 😂😎
Good vid
thanks!
But Goodson needs more money...
