302 casting swirl port heads

65Vart said
I may have asked you guys this in the past,but, I am thinking of picking up some 302 casting 318 heads (swirl ports) out of an 86 New yorker rather then getting my 273 heads re done. These have the right valve size so no need for notching the block. Questions are, will my push rods work or do I need a different length? do the rockers drop right on? will I need to do anything to the heads/block to keep the 10:5 or what ever it is at now?
Thanks in advance.

Be sure to check the exhaust manifolds by mocking them up to the head. This is very important on the "64" - "66" A bodies since the Drivers side manifold may hit the port boss or the bolt ridge on later heads and not seal, or worse, crack the exhaust manifold. And as metioned above, plug the smog holes below flush beneath the exhaust port.
