from just sliding it the spring on, i dont think it was getting caught on the seal but then again i wasnt aware it could catch on it. i'll take a look at it again.
Alfred,
Welcome to the world of high performance cylinder heads
1. You will have to get the Lunati retainers to match the spring.
2. You will have to either get rid of the "bottom bearing plate" which is called a rotator, and either replace it with a rotator eliminator or leave it out, depending on the original configuration of your heads.
3. Depending on the cam you bought, you might have to remove the heads and machine the valve guides so that the retainer will not hit them at full lift.
First thing you need to do is get the correct retainers and locks. Then take one intake and one exhaust off and measure the installed hgt with the new retainer. That will tell you what else you need to do.
There might be a single spring that will work with yur cam, but without the cam specs it's hard to say. Lunati can tell you for sure.
thanks boss.
