Can ramhorns be used on a newer style block?

[68jimmy]

Hello All,

the 350 that I have in my truck came from an 89 iroc z-28 originally. It has the center bolt valve covers and a a roller cam. I currently have a set of hedman headers installed and I'm thinking of installing a set of ramhorn manifolds... My question is since the newer style block have the oil dipstick in a different location will those monifolds work? Or should I try and find a set of manifolds from a z-28 or maybe just stick with headers? I have the regular hedmens and after a year or so the paint has peeled and they have that rusty look...

Is the ramhorns will work what are the casting numbers that I should look for in the boneyard?

thanks in advance
