Question 351w high hp with Ford only parts?

I've got a 351w from '86 and I'm looking to gain more hp without switching to aftermarket or cleveland blocks. Any suggestions? I've heard i can use the stock 302 boss heads without modifying the stock racing intake i have.

There's a little more to it than that....those years of 351's are smog choked engines...the block is fine, very strong, reliable, etc.......the heads are the key........assuming that the 302 heads you have are from the the 70's or earlier, if they have been rebuild, they have been milled, if they have been milled the angle of the head where the intake attaches has changed and needs to be milled as well.............but , in general, the boss 302 heads should work very nice with your engine provided you regrind the cam, etc.
