Help with head/cam package...
I just picked up some bare ported heads from CNC. I am going to have my local shop assemble, valve job, flow them, etc. I have a few questions. What valves/springs do you recommend? I was thinking 2.02/1.60's, but Manly, Ferrera, others? For the camshaft, would it be best to have the heads flowed and then call somebody like comp and have them grind a custom cam? I haven't found a place online to buy Ferrera valves, can somebody give me a link?
The car will be a DD, so I would like to keep streetability. Also going to bo with some longtubes, a stall eventually, and a dyno tune. Any other suggestions/parts that I am missing?
Thanks

Both Manley and Ferrera make excellent valve. Manley makes a Pro Flow version which have necked down stems right about the valve head. These improve low lift flow and would be my choice.
I believe Manley's site has the flow numbers posted; I know they're in their catalog.
Best way is to have the head flow numbers when you call CompCams. I'd only go with CC, they're king of the hill.
Make sure the guy flowing the heads properly calibrates the bench; I'm guessing you won't have any way to actually know whether he has or not, so you'll have to develop a friendship with the guy so he'll take a little extra time to do it right. Buy him a double-cheese burger and a shake.
Make note of whether he uses a clayed entry and an exhaust extension or not. The use of these effects the final flow numbers.
An even better way would be to have the complete intake setup flowed with everything all bolted together.

Thanks for the reply. We've dealt with the mentioned shop before when we had them do our heads for my drag car a few years back. They know their stuff. I will inquire about the way he flows them. Probably gonna go with a custom cam, Manly valves and have the intake port matched. Any others?
