First off i'll start out by saying i own a machine shop and occasionally do cylinder heads to sell on the side, this is a particular set i've done. They're 374 casting lt1 heads. They have 185cc intake runners. They've been machined for 2.00/1.56 valves, intake and exhaust have been ported (something similar to a stage 2 setup). They'll come with brand new Rev Stainless race 2.00/1.56 valves (custom back cut on the intake) and patriot gold springs with titanium locks good to .650 lift and 7/16 studs with guideplates. The intake and exhaust flanges on both heads have been milled to insure a proper gasket seal and the deck has been milled to a 56.2cc chamber after the chambers were redone. The guides have been cut down to accept .502 seals. The flow testing was done @28inches of water using Flow Pro software on a 4.030 Brezinski slider plate and 4.030 brezinski bore. The exhaust was flowed without a pipe. Numbers are as follows

Intake ---------- Exhaust
147.4 @.200 --116.0 @.200
207.1 @.300 --160.3 @.300
258.1 @.400 --175.2 @.400
264.9 @.450 --177.2 @.450
266.8 @.500 --178.6 @.500
270.6 @.550 --179.4 @.550
272.5 @.600 --185.2 @.600
275.8 @.650
278.8 @.700

Price is $1300 plus your heads as cores.

 

Heads have 185cc intake runners, 56.2cc combustion chambers and i'm about to upload a few pictures.

 

bump..... if someone already has the parts i can sell them unassembled as well.

 

ttt....

 

how much would you sell them for bare? or with just the valves?

 

Well i can take about $450 off totally unassembled. Or about $250 or so off without the springs/retainers/lock. If you have springs and stuff already and need them setup correctly i'd do all of that for free with the purchase of the heads. But still need to get another set of heads in on trade as cores.

If it would help anyone out i can accept most major types of credit cards.

I'll do $1300 assembled outright with no cores if someone wants them, got some bills that i need to take care of.

 

ttt... will also trade for ls1 or ls2ect t-56 transmission.
