Cylinder Heads for 290 horsepower 59 vette

[Patrick M.]

According to Corvette Restoration and Technical Guide for RPO 579, 290 HP the cylinder head part number should be 3767752; however, I cannot find this part with the above reference number. Does anyone know what part number should be used for a April 59 car?Thanks, Pat McPherson (55168)

The NCRS Judging Guide has 3755550 casting number as correct through June or July '59.

edit: I've seen a pair of 3755550s dated march and april '59 and advertised as Corvette heads on ebay. One of them has holes drilled and tapped in the end, which is not correct for Corvette. I guess you could fill the holes, but don't just install them based on the advertiser's claim that they are Corvette heads.
