Brand new lt1 castings, never been on a motor. Exhaust side has been gasket matched and ported. Intake side has had some bowl cleanup and the valve guide boss was blended.

No flow numbers yet as I just got them back and was going to have some more work done on them but decided to get a little crazier, so I'd rather someone else have these and use em as they are (would be great for a nitrous/supercharger application or a cam up to around 224/230)

I can give you the guys name and info that ported them.

Also:

Brand new Manley race flow valves, 2.00 and 1.56. Still in the plastic and boxes. These are the necked down valves for extra flow.

Brand new Crane 10308 valves with retainers, clips, etc.. in the box still.

Brand new Crane 99846 springs, never used but installed once. These are great single springs designed so no machine work is needed on your heads. Good up to .600 lift

Prices:
bare heads: $400
Valves: $sold
10308 springs: $sold
99846 springs: $70

All need to go ASAP..make offers! Prices plus shipping

 

will the valves fit a stock lt1 head?

 

Yep, you will need a valve job since they are a little larger than stock. Nice valves!

 

will the 10308 springs, retainers and clips work with those valves?

 

i'll take the valves and the springs if they fit those valves..e-mail reptileZ28@hotmail.com with your address again.

 

Sending email now. They're gonna make a nice addition to those rockers

 

im interested in the valve springs 10308 if you still got em

 

Remember you still owe me a set of heads since I lent you my spare set to have ported.

 

Yep, no worries. I figured when I pulled my stockers I'd have em hot tanked and ready for you
