Ran the flow test this morning
Here is the head mounted up on the SF-600 flow bench with test engineer Justin getting ready to hit the switch:
Flowing intake ports:
Flowing the exhaust ports:
And the results:
Happy to report the achieved flow numbers were inline with expectations so the larger intake valves and additional porting work paid off. Was especially pleased with the flows at lower intake valve lift points. The shop that performed the test had never seen a LT5 head before and was very impressed. Said it was right up there with the best SBC LS aftermarket heads they've tested on a 4.125" cylinder bore.
