Best Bang for the Buck Head???

I think it depends on what it should look like as well.
If you like Bling bling the eddys are ok.
If you like it stock looking there is no way around the RHS.

If your Pistons look out of the deck, you can mill them down to 0-deck.
with the RHS Heads you will have a perfect quench of .039.
CR is then around 10.5:1.
I had this in my 340 with TRW Pistons, milled .020 down to 0-deck.

I like iron heads because you gain more power out of them by less CR!

My next projekt is a 416 and i use the next set of RHS heads!
I like it stock looking and streetable.
Maybe this time i mill the heads a littlebit to gain little cr.

Fo me the Eddys are out of the race.
