Intake spacer and other upgrades

Dude, let me tell you, I did not know this. A guy I know is a parts, man at a Ford dealer been there for years, has hot rod Mustangs etc. Figuire he knows his $hit. Well I know the SO is a dog, e6's are more of a flow choke than e7's, the motor is a dog even blown.
Anyhow, the engine needs heads, so I ask him what he thinks, and he says he has a good deal on gt-40y's. Will they work? he says 86 and up it will, no interference problems. Told him specificly an 88 t-bird with an SO. He shows me in the SVO book. Cool. I call SVO and ask a Mustang racer at the dealer. Nobody had done it so they did not know for certain, but everybody said "it should work". Ok so the car sits for awhile and I finally get off my lazy a$$ to get it done. I pull the head off and see no valve reliefs, $hit, uh-oh, I better check. I did the lift test pretty quick but IIRC it wasn't even close. When the piston was at tdc the valve was like less the .010" from the piston. With the chain on I thought it might have even stopped rotating. No way I aint using these brand new heads and hose'n up the motor and heads. Big problem was I lost the reciept and the parts guy told me I was out. I didn't know about this board or hotrodding small block Fords. There were 3 different heads sold by Ford: gt-40x, gt-40y, gt-40z. The gt-40z's were the hottest, so I figuire the one in the middle like the alphabet cams. Come to find out it is the LOWEST horsepower of the three. I don't know if they're trying to trick you or what. I was pissed, :mad: I couldn't use Ford's $hit with Fords parts. None work with flat tops. Ultimately, it was my own fault, why? because I didn't check or take advise from someone who was running the same combo. Later I find out that TFS have more power, work with flat tops and are just better all around than anything Ford puts out. I thought I was doing good by going with Ford parts. It was an expensive lesson I'll hope not to make again.
I appologize if this sounded like a rant, but it was a live and learn deal.
