F Cam vs. B Cam

[90mustangGT]

A guy I know blew the engine on his LX. He's parting out his aftermarket parts and his mods are, or should I say were:

MAC CAI
C&L 76MAF w/tube
Accufab 75mm TB + EGR
Trickflow Street Heat intake
24lbs FMS injectors
AFPR
255lph fuel pump
F cam
FMS Shortie headers
H pipe
MAC Flowpath mufflers
4.10 Gears

I am picking up the 24#'s with his sample tube tomorrow. The only other things I see I would want is the fuel pump, and the cam which brings me to my question: Should I go the the trouble of swapping out cams.That is if his cam isn't destroyed would I gain any power over the B cam I have now.
B cam: 224/224 .510/.510 w/1.7's 112 LSA
F cam: 226/226 .544/.544 w/1.7's 114 LSA

It's the lift that bothers me. I have Thumper heads with the double springs, maby they can handle the lift but what I worry about is piston to valve clearance. Maby I should just trade out my 1.7's for some 1.6's with someone.

I'm not shure all of what he is selling, but if you see anything you want PM me and I'll send you a contact for him.

Anyone have experience with this? I doubt I will get the cam, just the injectors and fuel pump.

I would be real scared of installing a used cam out of an engine that blew - who knows if it didn't get damaged somehow (all it takes is a lack of oil for a few seconds)
