it all depends on your future plans. if you are just looking for a 300whp n/a car, the 1.90 valved heads will be sufficient. if you are thinking a stroker motor or a power adder down he road, then the 2.02 valved heads are the better choice to avoid spending money twice which unfortunately, many of us have done. on a side note, with the mild cam you chose and 1.6 rockers, you MIGHT be able to get away with the 2.02 valves without any modification to the pistons, but the only true way to tell would be to test ptv clearance when you get the heads. hope this helps.
+1 on the 1.90" valves. 2.02" are WAY too big for a mild 5.0. Even if you plan to make "big power" down the road. A 1.90" valve prolly won't be a hindrance.

if your plans are that long term for making more power, the 1.90s are definitely the way to go. the first set of heads i bought were a used set of twisted wedge heads. they had upgraded valves and springs and were ported on both the intake and exhaust side. i had that with a ported gt40, 70mm t/b, and a tfs stage 1 cam. to make a long story short, the car was a pig until about 4000rpm's where it really started to move. the heads were just way too much for the 302. i kept everything but the heads and dropped in a set of upgraded gt40x heads. the difference was night and day. now i have a set of afr 185's on the car, but then again its a blown 331 now. my point is if your plans for the blower arent somewhat in the near future, i wouldnt go with a head that outflows the motor and sacrifice the power now. just my .02Thanks alot for the input, I think I'll just go with the 1.90's. This is my first build up, so I'm sure it won't be my last... I'll probably try some AFRs in the long run. I'll be fine with 300 N/A RWHP for a while, I'd like to tackle suspension and other stuff after the engine build. I *would* like to eventually supercharge the car, but that won't be for years. Good info in those threads, thanks for the links.
we have all been there.....That is what I said too
Now that I got there ... My GT don't feel fast no more
