it's a visual reference for us to compare the port sizes. Pictures alone don't give good size reference so he's nice enough to put the sockets in there so we can see the difference in sizes.

The reason why I asked about the clover leaf style heads is that I want to stick with Phase I setup but use pistons and MLS head gaskets for the EJ205. To adjust compression ratio and match chamber to dish I want to modify the chambers but don't want to create any weak areas strength wise.

I might go for asymmetrical chmabers with maybe the clover bit only around the intake valves for cooler squish and go straight around the exhaust valves to reduce hot spots. What do you think?

That just says its big, doesn't mean it flows great.

Are the most recent pictures of finished heads?

oooooohhhhh....

We are quite aware of that, but something is better than nothing. The flow numbers exist and are there for reference, but the parts show just how much material he removed doing the porting.

are they standard sockets or thin walled sockets

I agree completely. Though I had used my 1" sand flapping wheel as 1" is 1". I like having an actual unit, since bottle caps and sockets aren't all the same size. If I recall David has used a quarter for his monster ports that he did years ago.

Just an idea for Fuji to use

well yeah but I used a standard 1" flap wheel as it's easy for someone to relate to the dimension and how much bigger the port is...when you have to force it into a stock B25 port

I use to snap to profile my ports consistantly. Then CC them for volumes and used the bench for flow to verify cylinder to cylinder balance.

But now I have no bench and thus don't do port work...at the moment.

FuJi, I've read thru your thread many times but I can't remember how you keep the exhaust ports consistent, what do you use for meassuring them?

Do you make molds for reference?

Just an observation, but: Just because a cyl head shows an increase in flow at various lifts, doesn't mean it'll make more power But you guys probably already knew that

Show the stock molds before and the molds you made after porting, with CSAs.

Then we can pump it through Pipemax and see what it says

120 grit too smooth? 80 grit is a little rougher

So if I were looking to get my heads mildly ported (D25's) in a year or so, is that something you do for people? Sorry, haven't read through every page to know if you offer up your services for hire or not yet.

PM me with some details if you do.
