Default winter mod questions....

so i got a killer deal on a set of GTP (Gallant Technical Performance) stock casting ported heads. i dont know much about the heads or the company and if anyone can chime in on if they are a good company that would be great. anyways, these heads are suppose to flow 265 intake / 210 exhuast, and i really want to run the gm-847 cam. the heads were used once before on a car, and i gave them a well known engine builder and racer here on the east coast, andy jensen. he bead blasted and hot tanked them. gave them a valve job and machined the valve spring pockets deeper for the right install height of the springs. what do u think the est. hp will be? whats the highest you can rev a stock bottom end lt-1? also i want to replace the lifters, which lifters would be best for the set up? also would a 100 wet shot send my motor to the grave or would it be fine?

6250 rpms is safe higher than that and you chew up main bearings
