Ok so the pockets on my 98 heads are factory fucked. Low seat pressure resulted in cam failure stock.

Machine shop shimmed a couple springs and they only came up to 100 lbs seat pressure, they're rated at 125 IIRC (comp 918)

Should I:

A) run em
B) try to find a set of heads cheap
C) machine a set of 5.3 truck heads to work (not sure of this cost)

or any other options?

 

member has 2000 heads for $75 plus shipping, I have some valve covers...

machine shop labor to finish shimming will be close to that I'm sure and I'll have subpar seat pressure, correct?

cam is a TR230 imitation, and I don't want to half *** this to the point I can't rev to at least 6500 safely because of shitty top end issues, what do you guys think?

 

241 casting LS1 heads are easy to find, bet there are a ton of guys with them sitting around and a lot with very low mileage.

 

Yeah, I just need a set cheap and quick if I go that route.

They would have to be shipped tomorrow and pref. 2 or 3 day UPS

 

I have a set of 241s for sale complete, $150 shipped.

 

I have a used set of PRC ported 5.3l stage 2.5 heads for $800 with springs or $600 without springs!

 

I have some 241's as well with new ls6 springs on them. I can swap them for some pac 1218's or 1518's or eave the ls6's on thier.

You'll pay through the nose for 2 day shipping on heads though. With ls6 springs 200 shipped or with pac 1218's for 300 450 for 1518's shipped.
