Crane Cams spring Kit 44308-1 For GT40 IRON heads

[hollywoodstang]

Hey guys.

I got another pair of GT40 heads i am working on and wondering if any of you used the crane cams spring kit 44308-1 with your GT40 IRON heads.

I have already purchased the kit and I have researched it but the answer was unsure everytime. Some went in without problem and some had problems(mostly with "P" heads) I am looking for someone who actually have used this kit before.

Let me know guys

Thanks
