were you referring to the part that they would lower compression?

it sounded like you were saying that 243s werent ls6s, i misunderstood

DMixer

thats why i need some help. I not familiar with new stuff. the last vehicle i had that i wrenched one was a big block 72 chevelle.

Are those heads worth buying, What would anyone pay for them?
Well i am on here, Does anyone know what cam comes stock in an 05 5.3

on the heads, core charges from head-porting companies like patroit, etc. are around $800, but used sell for cheaper but not much

I was agreeing that they are ls6 heads...and would prolly have to mill them to raise the compression back up right?

DMixer

he only wants $300.00 for them. Performance wise would it be worth it (with small roller too)

nightrunner

iTrader: (4)

right, they are worth the price, especially if he has them cleaned up and milled, like he said

nightrunner

yes it is worth it

what do you mean by small roller, if it means cam these trucks have a full roller setup stock

Thanks a bunch, have you heard much about the comp XFI roller cams for keeping drivability in a 4x4 w/35's

nightrunner

no i havent

do you have a link for them

the key to keeping driveability is not a certain brand or type of lobes on the cam but the duration and lift numbers, which you would want semi low duration numbers

id think a 212/218 or something similar would be good

I had just found them on jegs.com part number 54-450-11
