Pretty awesome for 151k miles :D http://i111.photobucket.com/albums/n...0truck/024.jpg http://i111.photobucket.com/albums/n...0truck/025.jpg The drivers side head when it was taken off it has a reddish coat on the rockers and the surround of the head... anyone know why? http://i111.photobucket.com/albums/n...0truck/026.jpg Passenger side looks normal http://i111.photobucket.com/albums/n...0truck/027.jpg http://i111.photobucket.com/albums/n...0truck/028.jpg Crap all over the place now lol http://i111.photobucket.com/albums/n...0truck/030.jpg Gonna send off my set of 243's that i am going to get worked over, my 5.3l heads with the prc dual springs, and one bad 243 head to Richard (the 5.3l heads and one 243 are cores) to Richard on Monday. Now all ill need is patience :devil: Ill keep yall posted when i get the heads back and let yall know how everything turns out :) |
Sounds good man...as for the "reddish" coating, I've noticed that the oil residue on the head with the PCV valve in the valve cover (driver's side) always seems to look darker than the passenger side on these engines...I've noticed this on other manufacturer's engines also.

Awesome man, Going to be a fun ride..
|
Awesome :D

definitely a badass upgrade, the truck is gonna run even stronger, now a cam would be needed to get full performance out of the new heads ;) you got the stall id got for it ;) |

Its getting the bigger exhaust valve but leaving the intake valve stock for clearance. LS7 lifters will be going on place of the stock ones. I don't want to mill them any more because they will eventually be going on an LQ4. So with having a 60cc head the compression ratio on the LQ4 should be around 10.8.1 with a stock gasket. Im leaving room for upgrading :D Thanks guys! Goal is mid 12's with these heads... it already runs low 13's in a 2000+ DA on slicks so with good weather and traction i could see it possible. Any lower than that will be icing on the cake :D |
