your 200cc Heads should be capable of running 11 sec street strip 383 sbc in 3350lbs carHQM383 wrote: ↑Wed Oct 20, 2021 6:39 pm Anyone had experience with these heads?
200cc, 64cc, angle plug.
I know they are old technology but for less than half the price of new modern heads like AFR or Brodix are they worth investing in with the goal a low 11 sec street strip 383 sbc in 3350lbs car?
What is the potential?
.... it would also be possible to Port your Heads to around 220 CC with better Flow Numbers later on
i may have Flow tested the ProTopLine 200 cc Heads , can't find Flow Sheet yet,
i do have Flow Sheets + these 2 brand new pairs of cast-iron 235cc ProAction_223400035A and 220cc ProAction_223200020A in my Shop
an Engine Builder/Machine Shop brought me 10 new pairs of the cast-iron 235cc ProAction_223400035A Heads
and said pick the best pair for yourself just for Bowl-Porting the 2nd best pair for him ,
all the rest he'll use them later on Dirt Track Engines .
