T/A heads
They’re already assembled, so the photo ops are over.
Pics of short turns are pretty much useless IMO.
Unless the SSR protrudes fairly significantly into the bowl, you can't tell by looking at them if they’re good or bad.
Tweaking the peak in a way which could be worth 10cfm or more, after the numbers have started to back up, won’t show up at all in a pic.
Even when I’m doing the work....... I don’t look at it...... it’s done be feel.
If I could tell by looking at it if it was good or not....... I wouldn’t need to flow it.
The bottom line for this style of head is...... at least with all the ones I’ve seen and done....... it comes down to how far you dare push the SSR back.
And this is why I find it much easier to get higher flow out of X heads.
The as cast SSR is laid back more....... so if you remove the same amount of material from that area of an X head and J head....... you end up with the X head having a lower and more laid back SSR....... which translates to higher flow with the way I port them.
As always......YMMV
If you blow up one of the intake port pics, and flip it over..... you can see the turn from that vantage point.
Everywhere you’d want to grind........to improve the SSR form, to help with the flow staying connected as it makes the turn........ there’s water on the other side of where you’re grinding.
