I have a post on unported all ready, this should be a good addition
my first set of heads i ported made my car slow down by full sec.!
If i would of had a converter and some gears it probably would have worked out good.
I sucked a valve on set of 360 head and made a real mess of one intake port.(valve ended up in the port side way:violent1
had to have one intake seat installed and had all exh hardened seats installed. clean up (ported) the bad intake port and then build some porting templates(like the W2 port temples) out of plexi glass and ported all the rest of the intakes bowls.
The hardened exh seats left a machining groove below the seat. ground one of them down and them made templets for the rest of them.
Pulled like a madman on top end! But destroyed all the streetable bottom end.

I'm getting my heads ported and was wondering how that worked for others ?
I sent my 915 stock 360 heads to Hughes Engines and got the stage 2 port done. They were on a stock stroke 360 in my Demon with a Hughes solid cam. It was completely stock weight with bench seat all interior. ( 3400 with me in it ). It ran a best of 6.99@ 98 mph in the 1/8.
Ran a 6.47 @ 107 on 47/53 jets (100 hp) spinning and drove to track.
