One set had blue stripe (correct)
Other set had no stripe, that's normally a tripple spring so I don't kkow what was going on

Blue stripe wouldn't be correct, the pac spring is a green stripe. We went through this when I got my afr's. My builder looked them up and he thought the stripe on my springs looked blue, which would have been a pioneer spring and he would have made me change. AFR discontinued use of the pioneer spring sometime late last year, when I talked to AFR he told me that there wasn't even a blue/black stripe spring (pioneer) in there facility when the order was placed for my heads, they were gone long before that. I placed that phone call to get it all straight to assure my builder, and had them send me pics of the pioneer spring with the blue/black stripe to confirm. The pac spring has a green stripe on them, if it has a blue/black stripe it is a pioneer spring.

Well, FWIW, this is what Jegs lists as the specs for the green stripe AFR springs. It lists a spring rate of 645 lb/in - does that sound right? Take it for what it's worth, I would verify your spring rates with a spring tester. It doesn't say if this is the PAC spring, so it might be something different.

BTW, have you verified that you have the inconel exhaust valves? At this point, I would be verifying everything about those heads.

I have no basis other than what my builder told me, but he said the pioneer springs were no good in his experience, and don't belong on anything over stock application. When he thought that mine may have been pioneer he said they had to be changed. I called Bob and he said that they were ordered with PAC Racing hydraulic spring, so I confirmed with AFR in detail as you saw that I posted. AFR went away from them for a reason. When did you place the order for your heads?

Teague marine is an oso advertiser too. He sells Afr heads that are truly marinized and machined. They will sell them bare, or custom to your engine . they are a little more than a automotive head with an inconel valve thrown in.

I finally confronted him this last time and asked waht was up. He pointed at the driver side cylinder head and said "where are the spark plugs ?" I said " I install those last" as I normally did/do. He walked off laughing. I was majorly like "WTF !"

Well, I get to the point of putting plugs in. Passenger side first and then the...uhhhhhh.....WTF !

Driver side was never machined for spark plugs. No holes even. "Really ?"

Yup, he wasn't making up his laughing. We was a Mopar Tech, so it was even funnier to him to see a Chevy guy get bit in the azz straight from Chevy.

Who would have figured ?

Off all things to fubar !

If I made it sound like it was a problem from AFR, I certainly didn't intend to. Wesseldyk always checks valve guide clearances and tweeks them in if he feels he has to on any head when he builds engines...it's just part of his MO and protocol.

I am in no way saying anything against AFR, I think they're great heads. :)
