MTI Stage 3 LS6 Heads, ~4k miles - $1000 SOLD
MTI 7.4" custom chromoly pushrods, ~1k miles - $50 SOLD
LS6 Valve Springs, ~1k miles - $75


Stage 3 ported/polished LS6 racing heads (2.08" Intake valves, 1.60" Exhaust valves). Custom dual-valve spring setup (Isky springs, custom titanium retainers). These heads made 550 RWHP on a naturally aspirated 427 with a 244/244 112 cam. They were used for ~4000 miles, and are in perfect shape.

I believe the combustion chambers are 65cc.

nice numbers.

 

thanks

 

Damn, if I was building another engine I'd be all over those heads. ttt for you.

 

would you sell the heads w/o springs?

 

sorry, i need to sell them complete.

 

bump up

 

What kind of compression are we looking at with a stock 346 bottom end and GM headgaskets?

 

you will need to do you own calculations, but I don't believe that the valves in these heads will fit in a stock bore.
