I have been working on a ported head solution for the 850's for a while now and finally have some good information.
I tested 3 Volvo B52XX heads
1 850 head
1 newer 70 series head with factory "D" ports
1 cj's ported and polished head (using a stock 850 head to begin with)
Here are the flow numbers.
I was able to attain higher flow numbers, but they are all but unusable with current readily available camshafts.
These heads will be available for purchase outright or with core exchange. Pricing and information forthcoming on my website. Inquiries welcome before information is posted.
