Had my X heads ported - results

Nice thread indeed!

In Stock classes it’s all about the best castings you can find!
All eight intakes and exhausts must flow identical and if possible outflow the best ‘of the best’ available...

Every casting has issues and some are terrible.
Flow benching a 100 identical heads would be mind numbing.

If you are lucky to get a pair of those ‘best of bunch’ heads, what a great starting point indeed...

I have ported about a dozen pairs of ‘J heads’ on the whole, they are all OK.
Picked up some cutaways from Weslake Eng. they are so helpful...
