MY CMW Stage II heads

I have a pair of you veary nice Stage II heads on my car, just got a 426 stroker, what is the highest lift that i can go with these heads, i love them, they came off a S/C jeep, silver

 

Scott said it "Should" but he needs to know what version Stage II's they are.

 

a 575 lift will have no problem whatsoever.

Scott wants you to call him at the shop on Monday.

 

I believe the cam in question is .590 lift......not sure if he'll have retainer to seal clearance.

 

Which is why Scott needs to know which version Stage II.

 

ok, thank you so much

 

You have to know what the piston valve reliefs are in the new 426. I'm running .609/.598

 

ok, i well find out on monday. thank u:ilovesrtc:

 

plenty of room in the pistons.The old cam in that motor was a cam of similar size......but the old heads were set up for that cam.

 

Thanks E:thanks:, i talked to AJ , he told me they should work, i brought the heads from him, but he told me that i might just have to change the vale springs, i hope this is the case:whistle:

 

Give me a call on Monday.

Those stage 2 heads will take a maximum lift of .570 It still has the factory valve seal. Those can be changesd to a after market valve seal if necessary. If you change them you will have to add a couple of shims which I can explain on Monday.

I would like to wish you and your family a Happy New Year.

How's your duaghter doing? I saw a post concerning your daughter..Hope she is doing well.
