hey would like to thank brett miller for all his hard work and time he put in these heads.. I took the heads to QMP RACING hear in so cal ..and had them flow this set of small valve w8s [[2.15]] intake .. brad at qmp was very happy with these number @lift flow
500 310
550 340
600 364
650 379
700 386
and this was flowed on a 4.200 bore fixture the flow bench at QMP is very tight my cnc 360-1 raise ports went 313 cfm on this same bench .. they were very impressed with bretts work .this port would reach 400cfm with a bigger valve




Wow those are good numbers for a small valve. I think they will run pretty good.
