I legit had a whole write up done
Oh well.
Have you built engines before? Do you have the specific tools required to do it yourself? Or are you just buying the ingredients for someone to put together?
The Skunk2 rods are very good for the price. Easy to get you out of trouble etc. but they are what they are, budget rods. For the price, I'd look at the Pauter rods or BC H beam extremes as they would be very strong and only roughly $400? more.
In saying that, a guy over here in Aus ran Skunk rods at 20 PSI on a GTX3071R from memory and made 300kW on 98 (low comp pistons) and had no issues what so ever. He had no mechanical sympathy at all and I think went through 3 sets of CV's.
My build recipe is JE 10.5:1 pistons, Argo rods (Aussie made, look them up), King bearings, ARP main and head stud, either OEM or Cometic head gaskets.
For head work I haven't really looked into it. Was mostly just going to change valve guides and probably put up rated springs in. Heads are pretty good, there's a little room for improvement but before long you'll be chasing power with wads of cash (porting and polishing).
Many reputable tuners have done all the hard yards to find the exact way not to blow these engines up. One of those techniques is limiting torque down low to save the stock rods from bending. This wouldn't be such an issue with a good set of rods though.
