I have a 302 in my 73 bronco that needs rebuilt.. my brother in law has a set of freshly redone 351 heads and intake... Will they work on my 302?
I am new here so be patient thanks

unless they are early 70's 351W heads they are not worth the effort you'll lose power if anything most late model 351W and 302 heads are exactly the same except for the head bolts most late model heads will have bigger combustion chambers which will reduce the already low compression of the 73 302. I'd stick with the 302 heads just get them reworked when you build the 302.

A good rebuild with a good cam will net you close to 200 hp on that 73. Stock engines in the 70's were detuned to cut down on emissions and such a few aftermarket parts really wakes them right up.
