Attached is the flow sheet from WCCH on these heads and comments from previous owner below:

“Heads were custom CNC’d by flowtech induction off AFR 225 blanks. 64CC chamber, as I recall they opened up a bit to 64.8CC. I had West Coast Cylinder Head bench test….report attached.”

Also you will see a brass sleeve on the intake side runners, again the why:

“After all this was sorted out, I was setting the valve adjusters when I noted the push rods hitting the sides of the push rod holes. After discussing this with Ed Curtis, I bought a few reamers thinking I could open them up slightly. Unfortunately in a couple spots the wall thickness of the runners became paper thin and one broke through (barely). I sent the heads back to flowtech and he installed the tubes.”

T&D 1.7 shaft rockers (P/N 20042) which I’m told work on these and OEM cathedral heads according to T&D. $1542 new) SOLD
Also included are the valve cover spacers to work with OEM covers otherwise you will need taller covers.

SOLD

FTI cam, see specs in attached image. No actual pic yet as it’s still in the engine and will be removed shortly.

$250 shipped

 

Bump. Have some interest but still have'em.

 

Rockers/spacers SOLD.

New price for just the heads in 1st post.

 

Do you still have the cam?

 

I do. The motor is actually still in the car and it will finally be coming out this weekend.

 

Bump for lowered price

 

is small bore 3.900 or less? how much?

 

I think in LS world another below 4.125 is considered small bore now a days but sub 4.00 is also considered small bore. These heads will work on and LS1 and pretty sure down to a 3.90 bore.

I’m going to hopefully CC the intake runner and chamber this week to confirm just exactly where these are at. They may actually be larger than 225 runners so time to be positive about it. I was actually told they were closer to 235cc.

Price is $1600 +shipping for heads only. The springs honestly seem just fine and I may just purchase a new set of seals as right now I have them completely disassembled to clean them up.

 

Cleaned up pics

 

Verified intake runner to be right around 236cc and chambers are a shade over 65cc as I had one tiny bb size bubble that did not purge out of the chamber.
