A quick simple question Idk the anwser to and just wanna be sure. I plan on buying AFR heads I know 185 would be best for 302stock/331stroked which I plan on doing in the future but right now I just wanna bolt them on and just worry about that later. So could I buy the 165s and when I am ready to 331 it could I send them to TEA and pay them to turn them into 185s? And if so and you have done this do you know what the cost would be?

I have exactly this situation and bought the 185's. Had them three years and have not put them on the 302. I now have the block for the 331....

They appear to be suitable for both engines, and my machine shop said I can vary the compression in my 331 with dished pistons if we need to.

Slap the 185s on....it will cost a lot more to port the 165s.

You're going to have more in getting the 165s worked over than you would with just dealing with the 185s from now. I'm not 100% on all the differences but I know the 165s are supposed to be emissions friendly so I'm sure there are a few differences there

The larger intake valves on the 185s may change your cam selection.
