The cylinder heads are $899.99 complete with valves & stock LS6 springs.

They are also available with double springs for a additional $250, or $159.99 for Comp Cams 918s

Will those flow enough for a 408 with your giant cam?

I heard they had a bad run with their porting not too long ago, did all this get cleared up?

I believe you have heard of another CNC cylinder head company having problems. We haven't had problems with the porting or components used---since bringing everything in-house.

PM me a quote shipped to 60108? I just over-revved my motor and may be needing some new heads (possible valve issues...will check out tomorrow in daylight). What kinds of lift are LS6 springs capable of?

Shipping is about $38 to you DC I have them in stock incase you need a set quickly The LS6 springs go .550" lift.

I would go big valves if I were going with a 408, the bigger bore on the iron block is just screaming for a larger valve

Will that hurt my 346 to go with the bigger valves now?
And can I get them minus the valvesprings? I alreay have the prc dual springs.
Have you guys put these on any magic stick equipped cars. just wondering if you have any numbers on a gain for the magic stick and these heads.
