Hey now everybody.
This is my first post and I am honored to be here.

I have a buddy willing to let a set of Gen5 heads go for pretty cheap. I am in need of a set of heads real bad, as I torched one side a few weeks ago.
I would be going from a closed 101cc chamber to an open 118cc chamber, thus bringing my compression way down... which is okay with me.

Problem is I am being told that my 1970's era block will not acccept a set of Gen5 heads. Something about the gaskets. I could be wrong, but the last time I shopped for head gaskets I don't remeber them being that block/head specific.

My question (if I haven't been cryptic enough) is; Can the Gen5 heads be run on my old block?
