LS1 w/ 5.3L 706 heads? Hey Everyone.
Im building an LS1 with parts from my 5k mile 5.3L i pulled from my old swap.
Are these heads any good for the 5.7? I did a search, came up with nothing good.
Im not looking to gain power with these heads, just want to know im not loosing any. Im only using them cause its all i have. If its worth it to buy a set of 853 castings i could pick them up.
Just want to know the 5.3L heads arnt going to loose much if any hp. Using them with 918 springs & a TR230 cam.
Sorry if its hard to understand, just want to make sure they will not loose much if any hp, or whether its a substatial difference to upgrade to 853 casting heads. I cant afford CNC heads so im just trying to get the best out of what i can cheap.
Thanks!
Sheldon
