Im looking at home porting my 862 heads and putting ls1 valves in them. The bottom end is rebuilt with floating pin rods/arp bolts and 4.8 pistons and a torquer v2 cam. I was wondering if i will run into ptv clearance issues with this setup? I have a stock replacement set of head gaskets for it also. if there is an issue with this setup, does anyone have any suggestions on what to do differently? thanks guys!

Its 3.78 bore correct , if so 2" valve will be fine no problem with cylinder wall . You probably want to unshroud the chamber. when you port them tho . Dont know the specs on that cam so cant tell ya , on the ptv clearance.
