862 heads
862 heads Came across these head on CL and would like to know how they compare to 243 heads.
862 specs
862 "truck" casting heads that have the Stage 2+ port job(fully ported)
Manley 2.02" intake valves, 1.57" exhaust valves
59 cc combustion chambers
Comp Cam Dual valve springs good to .650 lift (valve springs retainers and locks )
Looks to me like they are worth it but don't know what will be involved to get it to work on my car; Do i need to fly cut the piston, any other modification needed? As far as engine i have just bolt ons.
thanks for your help.

We have done a lot of work with ported 5.3l and they are definitely a good head. A ported version of 862s with the larger valves are a definite improvement over a stock 243 head, but if the 243 head is ported I would probably want to use that. If its not too expensive I would say grab them up. Piston to valve clearance would need to be measured depending on what cam you have.
Pictures added of the heads; do they looked ported? According to the info i found these were ported buy GTP but the shop owner changed direction and is no longer porting LS heads.

Are you kidding me dude? Even a peramiter bolt head ported like that would be worth 350. Good lord. I can't believe you needed to ask. Lol. Those valves, springs and retainers are worth 350 alone. That head work looks amazing. I would scoop those ******* up in a heartbeat.
