What Heads? BTR 4 and Fast 102 So currently my car is a cam only car with a BTR stage 3 in it. But this winter i Plan on changing to the Stage 4, throwing on a VR ported 102 i already have and some type of heads. Shooting for 450+hp out of a stock bottom end LS1. It is a 6 speed car with 4.10 gears.
I have been looking into the PRC 227's, TFS 220's or just doing a set of ported 243's/799's.
What do you all think the best option would be to make that type of power?

For that hp goal, I would think an aftermarket head (that has been worked over some) would be the choice. They also have more meat or material on the deck to help with strength and PTV clearance when milled. Much better starting point for removing material. Trick Flow, Mamo, AFR, and TSP are all great brands. I myself have 243 heads that were worked over by AI. Also a great choice, but it does limit you in some ways. 243 heads have less deck to work with if you consider milling. This in turn can affect PTV, cam size and quench. This actually applies more to stock bottom ends which don't have any piston reliefs or flycutting. AI and TEA are cost effective and a tremendous value. I love em. In the long run , I just think an aftermarket casting will offer more options and be easier to customize to your personal needs. So I read.....lol good luck

This just solidified my point. You do not need a larger cam to hit your goal. Put the money in the heads. TFS 220's or Mamo 223's and a ported Fast will get it done. Buy good lifters and make sure the push rod length is right...you will hit 470+.

The btr stage 3 and 4 specs sre pretty similar. I doubt it would be worth the time to swap them. Brian has strongly recommend his touched up tfs220's to go with my btr stage 4

As others have stated, the TFS 220's worked over by Brian Tooley would be an excellent choice. Another great option would be Tony Mamo's 223 Sportsman head, which comes in around the same price as BTR's TFS 220's.
I do not think it would be worth the risk shipping your already ported Fast102 just to have it port matched to your heads, although the transition between the two is important and should be as close as possible. I just do not trust the postal service when dealing with polymer intakes, and VR's porting services are sure to provide some measurable gain over a non-ported intake even if the ported intake is not port matched to your heads.
I, personally, would honestly get the MMS223's, keep the Stage 3 cam, install the VR ported 102, and make sure the thing is exhaling through a nice true dual exhaust system.

Im still on the fence about changing the cam. I found a BNIB stage 4 local for cheap so i grabbed it just in case. Could easily resell and make my money back.
I definitely dont trust shipping my intake out when its already ported, had to many bad experiences with things getting damaged. I would rather make up the Horsepower lost swapping cams.
My exhaust setup will be 1 7/8 LT,s ORY, possibly flow master merge into SLP LM2 into CME.
Everyone seemed to be leaning towards the BTR TFS 220's. Ive talked to Jared and thats what he recommended to me. So most likely that will be the route to go.
