I've got a set of Aluminum truck heads (317s), hand ported by a friend of mine at SAM. I'll also throw in a set of REV Stainless Steel Valves and a set of Comp 918's, NIB. Take it all for $1100.

Flow Results:
28" of H2O
4.030" bore
2.02" Intake Valve

Lift int. exh.
.200 168 ?
.300 226 ?
.400 270 ?
.500 301 ?
.600 316 ?
.700 332 ?

Pm me if interested.

Look again. Add $150 for the 918's and another $100 for the valve job, thats now $1150 (without shipping) and your still almost 10cfm less than these heads.

Not to mention, that doesn't even give the bore size those were flowed on. Can't really make a fair comparison without more info. But just for arguements sake:
PRC's w/ 918's and stock valves
307 cfm @.600"
$1149+shipping

Ported 317's w/918's and REV 2.02"/1.60" valves
316 cfm@.600"
$1100 shipped

BTW, I AM NOT trying to lowball a sponsor. Just trying to get rid of some heads I decided not to use.

 

I wasn't saying the TSP heads are better, I was just showing you the link because you asked for it. Those heads you have put down some good flow numbers, valves are to big for my cam though. Someone's gonna be fast with these
TTT for ya

 

Thanks,
I'm just selling these to free up some money. $1100 is negotiable.

 

bump.

 

Hmmmm, no one?

 

how much lift can the springs hold how negotiable?
