Rookie49 Posted January 12, 2007 Report Share Posted January 12, 2007 What kind of heads are cast iron, fit a chevy 350 and have the valve cover bolts throught the middle of the valve cover? I'm just curious and don't want to pull the covers to look for a number. Oh yeah they are mid 80's probably. Link to comment Share on other sites More sharing options...
Guest Top Dog Graphix Posted January 12, 2007 Report Share Posted January 12, 2007 maybe 993 heads.. Link to comment Share on other sites More sharing options...

soaker Posted January 12, 2007 Report Share Posted January 12, 2007 A 993 head does not have the valve cover holes thru the center of the cover. Atleast none of my 993 's never have. Those are vortec heads 1988 and later.Call me rookie. Link to comment Share on other sites More sharing options...
Truck99 Posted January 12, 2007 Report Share Posted January 12, 2007 Could be Vortec head (906 casting) or non-vortec closed chamber crate motor heads like the 217 or 083 castings. Definately not 993s. Link to comment Share on other sites More sharing options...
Guest Top Dog Graphix Posted January 12, 2007 Report Share Posted January 12, 2007 oops, i was thinking 193... but the list of centerbolt heads i know of are 081,083,087 193 & 217 081 heads came on 305's your best bet is to pull the valve cover and find out, its only 4 bolts! 14096217...55-86...350..........Crate motor, 285hp/300hp, 64cc chambers, 72' or 90' center intake manifold bolt angles 14101081...87-95...305 14101083...87-up...350..........Gen.I, also used on crate motors, 285 or 300 hp, 64cc chambers, 72' center manifold bolt angles 14102193...87-up...305/350......1.94"/1.5" valves Link to comment Share on other sites More sharing options...
