So Jay, Are you going to put a set on your 460+ block?  How much do they cost? Are the Intake & Exhaust bolt patterns as FoMoCo? What size valves? Do these guys have a web site? I think your pics were GREAT!!!
Thanks for sharing!!! Ryan

The heads are bolt on replacements for A460's, however the chambers and ports are different. They bolt up to a stock block but take an A460 style manifold, which they also make. The rockers are stock but they take special guide plates and custom length pushrods. And I found out you need TALL studs to clear these monster valve springs. The regular length BBF parts are at least a half inch too short.They guys that make them are Flow Technologies and their web site is... http://www.flowtechnologies.net/ They basically told me that these heads, out of the box, are what you would end up with if you got some A460's and did a major port job. They used a set of tricked out A460's as their guide. The entire package for heads, and manifold, complete with there "stage 1" hand work in the bowls and chambers is about $3700. Not cheap, but a lot more head than CJ's or Blue Thunders. ------------------

These are going on a 545 that I have been collecting parts for as fast as the wallet allows. The cam will be a solid roller, 260/268 duration at .050 with .726 lift, ground on 112 lsa. Should be stout.

F551, you are correct, those babies are either out of there totally, or at least are going to get a serious trimming. Chances are a Mustang II setup from Rod & Custom will be going in there.------------------

Hang on.... these are for a street car or race car?I don't think they are an ideal choice for the street ,for a race car that cam may be too small to allow the heads to even work right.

These are for a street car guys, that will see occasional track time. No doubt it will be one rough sounding bad a$$ motor, but thats the goal. I have always wanted to build a ragged edge street car, one that scares mothers and small children.  The heads, in there current state, go turbulent somehwere close to .750, with port work they are good to .850. However, the flow numbers at .700 are 415 on the intake and 312 on the exhaust. I picked the cam I did because it gets past .700, but not by too much. By more cam I am guessing you guys want to see more duration? There is a similar cam, same lift, but the .050 duration numbers are 268/276, would this be better? I am basically copying a motor that Summit Racing built a while back and posted an article about, here is a link to it. http://www.trickflow.com/articles/stroker_3/at_st_3_body.htm The only real difference is that my motor is 25 cubes larger than the one in the article. That engine dynoed at 752hp at 6250 and 660 ft. lbs at 5250. It also had a nice flat torque curve, hitting 540ft. lbs by 3500 and never looking back, the motor was still making over 600ft. lbs at 6500. The cam in that motor was a crane solid roller, with .718 lift on both lobes, and 268/278 duration at .050, ground on 110 lsa. I could just use this exact cam. ------------------
