Heads..

2.02/1.60 valves and a really good Port job to intake and heads. Is that what i need to do?

With the stock 400 heads(1.94/1.6) and me home porting then I only got 13.2's on a 406 bottom end,5.7 rods,9.5:1 compression,280H CompCam.

Went to 200cc Protoplines,(2.05/1.6, bone stock (smaller cc chambers) so about 10:1 and went 12.3 (only change made)

Now heads shaved a fuzz,bigger valves(2.08/1.6),solid roller, with a best 11.3 to date.

Alright.... what's your thoughts on the cam I'm running

Skunkworkx · Posted: Tue Apr 19, 2011 6:15 pm Post subject:

I like the cam.....but those heads aren't much better than stock heads IMO
I'd look at some 200-215cc heads (leaning more towards the 210-215 for a max effort with no porting)

Dart 215's
Profiler 210's (w/ econo-port job)

i was planning to port these s/r heads myself... you think i could get them to flow 215... and is the exhaust side not important cause nobody ever list how much that side flows?

Decided to play with Excel and put my airflow numbers in a chart like the Profilers. Kind of interesting to look at that way.
