Im email KMS to see what valves it come with. KMS is 475 and that comes with All casting marks in the air ports are removed to help increase airflow speed. The head is ported, polished, and glassbeaded to smooth out all minor flaws.
Depending on stage, you also receive race valve job with 5 angle intake 3 angle exhaust. The head is also flow tested in house on our flow bench. The final step is to deck the head by flycutting it.
And exospeed is $735 and it comes with Full Valvetrain Upgrade. Isky Titanium Retainers and with performance valve springs. 3-angle valve job as well as hot tank, new valve seals and resurfacing the head. 9000 RPM Ready!
If anyone has gotten this done then i will like to hear your opinions. I want to do a through research of the topic to find out where i can get the best deal.
