Yes , I'm with Blown06 on getting what You paid for , if that sometimes . Unless You're doing a portion of the work Yourself which it does'nt sound like You're doing .

 

x2, also working on sbc stuff for years doesnt mean that they know what there doing comparably when talking LS stuff imo..
plus it almost costs as much as hes charging to get a decent set of springs, thats what would make me weary in the first place..
where are you at in IN?

 

Aint that the truth, sbc's and GENIII's are like apples and oranges...

 

Take that $280 and put it in your transmission/torque converter piggy bank, imo. The stock heads with upgraded springs will work fine.

 

Hey guys , I found a place with brand new GM ls-6 yellow springs for $59.00 plus shipping . I can't say where on here , but if You get me You're e-mail .

 

I dont know about the $280 work with springs. springs will cost ya $120 to $255 for good springs. I would not trust a person that has not put the R&D into the flow, and power output of the port work they do. I like WCCH, Richard does a lot of r&d before he sells you his work, but it will cost ya.
