Good points.

Hey, thanks.:drink:

Every once in a while I get things right.:nuts:

Joe has the intake with the blower, but does not have a carb for it anymore. He suggested a Demon Holly 750. Anyone, anyone?


I will begin looking for a smoking deal on AFR 190s~ to get a feel for how much they will likely be.

Or maybe just a pair of these, as BRUTAL originally suggested.

AFR is the best for the cost.



These are the heads I actually suggested. Now these are China heads. They will probably need some work- quality may be an issue ( I haven't seen these head myself)--but the price is right. I know some of you guys don't like china heads. :judge:

I just talked to Troy at Ford Performance in Anaheim. They're a speed shop in Anaheim that build motors of all types, but somewhat specialize in Ford. He helped me a bit during my Corvette build.

I talked to him about our build and he recommended off the shelf as cast Avenger Heads with 195 cc runners, Fully assembled including shaft mounted rockers: $859 for the pair. They were going for like $1199 and up recently, but the economy ain't so hot. They are brand new aluminum heads. He says he uses them on their crate NA 347 for 440HP. Plenty of head for our application.

This seems like the way to go, the AFRs are just a bit much. Any thoughts?

He had two questions. What are the pistons? Something about making sure they had the proper valve relief. He said as long as they were aftermarket pistons there should be no problem. Also, he wanted to know about the cam so he could set up the spring pressure properly.

Keep looking or pull the trigger? This represents the upper end of my budget for heads.

Yep, most aftermarket heads are interchangeable now. You just have to purchase the correct head bolts/studs.

I don't remember and can't find the paperwork to determine what pistons I purchased for this engine. They are definitely aftermarket pistons. I'm pretty sure they have valve reliefs cut in them, but you'll be able to see that when you pull the heads anyway.

Again, I can't find any specs on the cam, but I would be very surprised if it had more than .540 lift on the exhaust side, and no more than ~230 - 240* of duration at .050 on the exhaust side. It would be less on the intake side. This was a pretty mild cam.

That sounds fine to me. I won't know till I look at the head if they have possiblites. Even then I can only look for MAJOR problems with the Port shape and bowl area. Does he have some flow numbers? I can look at those (if the flow numbers are correct) and get an idea what it will do.

They are probably fine, your call. Like I said, we can make anything work here.:drink:


Just need a good starting point. They will be better than any stock head I could port.:)


Saturday after the run I could give a Porting 101 class. Someone just needs to bring a pad (big) and pen.

I couldn't find the 195cc version on their website, but I looked at the 185cc & 205cc. The 185 flowed 274 cfm on intake and 190 on exhaust @ .550 lift. The 205 flowed 290 cfm on intake and 223 on exhaust @ .550 lift.

These heads are "as cast". They need to be ported for maximum awesomeness.

We are going with 195 (I think).

Here are the flow numbers for his CNC Ported 185:
Lift:cfm-in:cfm-out
.100:69:59
.200:129:118
.300:188:153
.400:234:178
.500:269:189
.600:278:195
.700:281:210
.800:288:228

For his CNC Ported 205
.100:71:61
.200:142:124
.300:190:162
.400:252:200
.500:287:218
.600:300:225
.700:305:230
.800:309:235


So, I sort of infer that our flow numbers for a 195 and .550 lift would be
284:207

How's dat?
