looking to find specs on 340-X heads.

I would buy a j head over the infamous ,lol, x head as their crap to begin with as your flow #s dictate, buy a set of eddies or victor if you want to go faster than 12s in the 1/4 mile. no offense meant but the x heads are way overrated and way misunderstood .

OK, soooo, Edelbrock makes Victor heads for a S/B engine? Fishy's head flow numbers are preety nice for a OE head given very little in the way of a performance treatment. For the price, there a good bang for the buck.

..#2 they came with 2.02's...o's,j's,u's never did 1.88's only

I have had alot of people stand up and shout different. I myself have not seen a 2.02 in those heads. But if the heads come cheap, adding a nice set of valves and even a pocket porting job, the price is good and performance is nice, a compareable bank for the buck agianst Edelbrock heads.

Dartmans $350 for the heads are not a bad price to start with.
