Which vlave spring kit would i need to purchase for the TN227XR cam that is going to go right on the stock head with no problems? I also plan on getting 1.6rr Which should I go with the Self aligning or the non self aligning? thanks for any help.

 

The only "kit" I know about is Crane 10308-16, but you'll have to give all the cam specs for someone to make an educated suggestion.

 

sorry

Combination Motorsports Comp Cams TN227XR Camshaft

Grind # LT1 3441 / 3442 HR114+4

These specs are for cam installed at 110.0 intake center line

Then the Crane kit will work nicely.

 

Will it also work nicely for a CC503? What spring locators (seats) are required? Anyone know the part number for the seats or the correct valve seals by any chance? Thanks for the help fellas.

 

Valve seals are determined by the valves, not the springs. Any engine shop should be able to get those for you.

I believe the Crane kit is meant to work with stock seats.

 

Stock valves. Thanks for the answer about the seats.

 

Wait, what about clearance issues with dual springs? I want to know if stock valve seals will clear under the Crane dual spring kit?

 

I've never used these, but I would think that Crane thought of that.

 

it can be a drop in kit. there is no need for anything else at all.
stock valve seals will clear. if you got higher mileage go to your local autoparts store and get new ones. i never had a problem with the crane dual springs in the 10308 kit and the valve seals i got from autozone. they should be able to find the seals through the computer at the store. otherwise i think i looked them up on shoeboxes site a WHILE ago. can't remember.

 

Thanks. I went ahead and ordered felpro replacements.
