wow thanks for the info guys. now im completely confused of what to do. i figured this would be good upgrade based on how well his motor ran with them.

the only prob i have with my motor is the loud lifters when i get down on it. makes a horrible noise, but nothin a loud radio doesnt fix, cus despite the noise itll still smoke just about anything around my lil town. not knowing much about the motor is was goiing to build my own for it if i were to keep it, but not sure, so was trying to do the budget thing. i have 3 trucks now, so its a hard decision.

it does have hei, i had alot of trouble making it driveable , timing issues. but they cleared up alot when i put the supercoil on it and i been running the hell out the truck ever since. by now t might have a bent pushrod or valve, not sure, but it pops from time to time when im starting it and wasnt sure if its popping back thru the carb, the leaky headers, or if its the lifters cus the exhaust is so loud, its hard to tell.

im guessing 305 vortec heads are worse too, seeing the compression thing and ill have to go back with a pretty close to stock lift cam to keep from spending alot on millwork. this is what my bud is upgrading to, but with over $400 of millwork.
