New member and have been lurking for a while.

I have a 99 SS A4. I just had the bottom end rebuilt. Would be happy to break 400, but 425 RWHP would be even sweeter.

Adding:

TSP 228R cam
LS6 intake
243 heads
Speed Engineering LT's
Magnaflow Exhaust

I'm stuck on whether to port the heads now or save it for elsewhere (bye bye 10 bolt).

P.S. Just put in a Yank 3600 stall while the engine was out.

If it were me I'd have the heads ported now

Which is where I'm leaning. I know 425 is a stretch, but just want to ensure I hit the 400 mark.

I wouldn't worry about a certain dyno number. If it's setup and tuned right it will do what it should regardless of the dyno number

I just finished a very similar build

-ported and polished 243 heads milled .030 for 11.1 compression.
-Fast ported 92/92
-1 3/4 qtp headers through magnaflow cb
-tsp 228r 112lsa
-M6 tranny through moser 12.bolt 8.8 trutrac

I dynoed 428rwhp/396 ft pnd torque

With an A4 i think youd be around 400-410 rwhp.
