Howdy all! Just took on a project (read money pit!) 79 K5 Blazer that I picked up CHEAP. It has an 89 shortblock in it and I have a set of decent 74 heads, Edelbrock torker intake Holley 600 (I think). I've done a good bit of searching but am still a bit unclear, will the older heads go fine on the newer block? Please pardon my ignorance, I've built some engines before but never a Chevy.
