I am debating if I should get the boss 302R cylinder heads I just don't know if they will even make a difference performance wise

No, have yours ported, you will get much better gains.

umm...depends on if the person you are going to knows how to port and polish heads and do a 5 angle valve job.

i'd imagine the heads are probably pretty expensive to buy for little horsepower gain.

It's whoever Truestreet sent them to I believe somewhere in Houston. And the engine isn't together yet so I don't have any numbers

Oh ok, didn't know if that was something you had previously done. Have you got an ETA on your car?

To put it into perspective, a bone stock 2013 manual 5.0 makes around 390 ish rwhp.. (Just an average number) a 2013 boss 302 makes about 405 rwhp (again just an average number) so that's 10-15 hp over a std gt car... Although the entire power band is different but you get the point. Get your heads ported there will be much better gains.

BLK2012GT get flow numbers on the heads before and after as that'll be helpful to all of us. Also will they be port matching the heads to your intake? Thanks!

I'll find out some numbers but I believe he ported ones are flowing 30 or more CFM over the stock heads.

Do any of you guys know of a good camshaft that's good for daily driving I was looking into the ford racing exhaust camshaft
