Got my AFR 220's/T&D shaft rockers in 3 weeks WOW I expected 6-8 weeks [img]graemlins/hurray.gif[/img] . Removed stud rockers and started to setup shaft system per t&d instructions- ok no shimming or milling of heads [img]graemlins/thumbsup.gif[/img] .

Then I try to test install head bolts. The center cylinder exhaust springs looked pretty tight especially with large roller springs.I could not get the arp washer to fit(I have the correct 12 pt.arp's) Machine shop told me that's common, just remove the springs and grind the metal internal locator washer and/or headbolt washer slightly.I removed a spring and found TWO stacked on eachother! They are raised in the center so can not be stacked!!

Lucky for me I had to remove this particular spring!

Any way I removed the extra one,clearanced the washers and all is well now.

Has anyone run across this?

Ray,
I would take each and every spring off and examine the assembly. Probably would not hurt to check installed height and pressure also. If you found one double spring seat, whats to say there isn't another somewhere. By the way, I hope you replaced the valve stem seal on the ones you removed, looks like half of it is on the end of the valve [img]smile.gif[/img]

Thanks Bill, I checked the other ones visually with a surefire flashlight and this was the only one.

Other then the double seat the heads look great!The casting and machining are very nice. Tech support at afr so far has been pretty good,nice people.

That white stuff you see on the valve stem is teflon pipe tape. I wrapped the groove really well then oiled it and removed the seal very carefully [img]smile.gif[/img] Didnt damage the seal.

Thanks again, Ray

Nice heads!

Which headers are you going to run? After seeing Torkers problems trying to fit headers on his 210's going with the staggered bolt flange arrangement might have been easier in the long run.

Thanks CarlC! Yeah the heads look really sharp, but I am more impressed with the rocker shaft system. It centers the roller tip exactly on the valve!

I will be using hedman 1 3/4" headers ( which I currently have on the car now with my stock engine)I think it was pt# 65003. Made for angle plug,air cond, and power steering.

Most headers will bolt up, the problem with AFR's is the port shape. If the 220 shape is the same as the 210 they are wider than they are tall. Most header ports are taller then they are wide. It makes port alignment tough. Hopefully the Headmans will work without too much difficulty.
