Hey whats the going rate for a valve job and will there really flow 230-240 with the valve job i didn't think they would pick up that much flow. I was thinkin more of 170 to 190
With a bowl blend and gasket matching BJR siad. I thought the J head flows around 190 stock on the low side. Some people have posted 215 as a high on a 2.02 equiped J head, no other mods.
