Is the entire Chevrolet Performance 350/290 crate engine considered a Generation 1 small block with Gen 1 style heads etc, or is it a mix of new and old?
The heads use the Gen 1 valve cover pattern, so assuming they are Gen 1 (unless frankensteined), but if they are Gen 1 - why does Chevrolet Performance not seel just the heads? I've searched and Chevrolet Performance doesn't seem to sell them - the Chevrolet Performance new gen Vortec heads always come up for sale - but not these ones.
Thanks for any info.
