Heads are 317 castings and come with 2.02/1.60 Rev standard length valves, port work done by me. Intake runner is rolled finish, comb chamber and exhaust runner are polished. Deck has been surfaced, just to ensure true ~005. Intake runner volume is about 236cc. Flow numbers are listed below.

Intake Exhaust
.200 151 114
.300 210 157
.400 253 180
.500 293 206
.600 315 212
.700 318 216

Flow numbers came from Trevor Johnson cylinder heads. He has no allegiance to me and will confirm flow numbers if necessary. I have the flowsheet in PDF format for the purchaser. Heads come with valves and you supply your valve springs/retainers. If you need it, I will install your hardware at no additional cost. Make no mistake, these flow numbers are dead on, not like many of those shops that claim numbers like this and fall 10cfm when on the actual bench. $950 shipped, $900 picked up in the Garland area. 469-387-2576.

still for sale.

 

are these heads LS6 or 6.0 heads?

 

What is the cc size and what bore size are these for?
Thanks
Ray

 

CC is 71.55cc. They were just resurfaced. Optimum bore would be 4.00/4.040, but they will work with a stock bore (3.9) if milled down some to get compression back. The 2.02 valve doesnt shroud down to stock bore size. The larger the bore, the more compression you get back.
