Trickflow as cast 220
FWIW we sell the As Cast 220's with PM guides, PAC dual springs, and Ti retainers for 2075.00 shipped. Used to sell them cheaper until the pricing on valves went up.
We've put together a lot of combinations using these heads with great results.

2075 with no hand blending and a PACor 2100 with Brian Tooley blending the valve job and chamber and the comes with BTR Springs.... Yea... Id spend the extra 25 dollars for that with LJMS in a heartbeat...
We also sell those heads with a PAC Hot Rod 1200 series spring or a 1204X RPM Series Dual Spring both with titanium retainers.
As far as changing the cam, it would really depend on how many miles a year you drive your vehicle and how you use it.
Good observation, hence why Id pay more for Brian to touch them if and when I get my next set of TFS

Thanks Martin. As far as miles its a weekend car and test and tune at the track when I get the chances to go. Already been through one set of springs(prc dual) in 10k miles now it has btr dual with about 500 miles. If I could get 15-20k out if springs and other valve train parts I'd be ok with that.

I'm not sure if BTR actually does more hand blending for 2100 or if he charges more for that. If he doesn't that is a very good deal. IIRC Brian told me at one point that he charged more for his hand blending, but that was before valve prices went up.
The 205s do include the PM guides. And they are fully CNC'd for 1995. I would recommend them over the As-Cast 220s. They flow pretty similar, but you have a lot more compression with the 205s, and a smaller CSA for better throttle response. Had I known about them, I would have went that way over the TEAs I have. I wouldn't have had to flycut either, and I would have a lot more compression - 58cc with stock PTV clearance.
I have been emailing back and fourth with Martin and he said the 64cc 220's with .040 cometic gaskets will put the compression at 10.9:1. He also said that I could go down to 63cc for 11.1:1 compression and still have plenty of PTV clearance. I am thinking about going with these heads and a 229/231 113+3 cam that Martin spec'd.
Thoughts?
The more compression you can get with adequate piston to valve clearance will yield you more HP/TQ across the powerband.

Just curious what you mean by "a lot more compression"?

The 205s come with 58cc chambers at stock PtV. They would work very well with something like the Polluter V2 which needs 11.8:1 CR to work well. The smaller port will yield more velocity as well. Which will help with part throttle, where big cams suck. A 205 port that flows over 300cfm will easily support 480+rwhp on a 346, so it's a very good head for big cams like the Magic Sticks, Polluters, Donkey Dick cams of the world. It's CNC'd, has PM guides, and the port design and small chamber are a very good match for big cams. It's also cheaper than the TFS As-Cast reworked...
