OK...most likely a real stupid question...but here we go.....My 401 is in the shop being bored,balanced...etc. I have INDY SR heads, and an Edelbrock RPM air-gap intake. They mocked it all up today to check pushrod length,intake fit...etc.GOT really WEIRD...the intake gaskets line up just fine on the heads..BUT are off on the intake manifold,the manifolds ports are offset. He says the intake would have to be welded and machined to line up correctly with the gasket ports!! My friend who is doing the machine work says that they run into alot of Edelbrock port to gasket opening mis-matching?? NO quality control????WORST DEAL.........the end rails are 5/8" off?? There is a 5/8" gap at the point where the intake end seals are to be????? WTF?? I know the INDY heads are somewhere around .500 taller than stock heads...BUT how can the intake surface fit/line up correctly BUT the ends be that far out of whack?????? Am i missing something here..or is the manifold a piece of @#*&(^%$#$^& ?? I have to drive one hour tomorrow afternoon to the shop to look at this mess(Thursday). ANY helpful info greatly appreciated. Please email me or call my cell and leave a message....309-338-3210.Thankyou,Joe __________________________________________________ Do You Yahoo!? Tired of spam?
