So basically I want to clean up the casting imperfections in the head, just want to make sure this stuff is ok to remove before I start! I had a mild p&p done last week, figured he'd do this stuff but ah wellz, shouldn't have said mild! here's the imperfections I'm talking about:


Thanks for the input!

 

Honestly, I don't see how that would help in any way. Does anything flow past those points besides oil? Correct me if I am missing somthing.

 

No that should have no affect on engine Flow. Take pics of the ports. Lets check those out

 

I'm not looking to improve performance really by cleaning up those imperfections, just to clean up and improve oil flow within the head .. unless this will accomplish nothing, in that case I'm ready to assemble! hehe.

anyone support their reply?

 

cleaning that part is worthless

 

Yep. Almost every B head ive seen has that one on the left. It will do nothing if you smooth it out. If you want to get rid of something, get rid of the casting marks on the sides of your intake/exhaust ports... you know what...wait... nevermind.... dont.

 

I've actually seen a couple of heads where some of that casting is about to flake off. I usually try to remove it if the head is out and being cleaned anyways. Definitely won't hurt anything.

 

That's more of the response I thought I'd see .. if it prevents anything or improves why not? I have the head out and it won't hurt it .

 

I say do it....

I did it the quick and dirty way which was using a small flat head screwdriver and just gently tapping on some of the casting imperfections and they came off really clean.

I figure after who knows how much mileage - the imperfections going through numerous heat cycles, it's better to be safe than sorry.

Endyn does it with their builds.... but that's another can of worms....

 

hehe I'm no Larry, but I figure I can dremel out that stuff to prevent any bits getting into the motor .. head is completely bare so I can blow/clean off any shavings etc. I'll post my work up next week after I get the head back here.

 

like said above, it can be beneficial to remove the flakey pieces of metal along the casting seams or sharp corners. sometimes, those little pieces can break off and get in your oil. Some head porters will give the head a once over and grind off those edges for you (usually called "deburring").

 

yea i was reading about how endyn would usually go over the head and take out any casting flaws that can be safely taken out. hey it wont hurt. but at least you get some peace of mind

It's nothing significant I know but there were some areas where the pieces were not solid, so it's not a bad idea to do this imo, if you're spending the time and money to build the motor from scratch. Will it make a difference? Probably not, but it is better than before.

 

Is it? Exactly what was improved/what will benefit from this?

 

i think if you have the time and the ability, go ahead and do it, a buddy had got a dart block and had to do this to pretty much every hole

Perhaps marginal fluid flow...but more importantly if those pieces break off.... they're likely to cause "issues" down the road.

As it was mentioned prior, it's done more for the peace of mind for the builder who sees these imperfections as debris that could potentially break off ruining a build.

Will it give you more power? No....

Have these pieces been proven to break off causing motors to go boom? No....(rather, none that I am aware of anyway)

Is there a chance they could break off and cause damage? "Anything can happen....."

 

It's really to each his own here guys, I saw something I didn't like, so I removed it, end of story. I do expect roughly .01 whp though.
