302 heads

CNC porting is over-rated, especially on a street motor. Anybody who knows anything about boundary-layer physics would agree with me. Chamber design and port geometry are more important.

so the headers i have will fit the trick flow that comes in the kit

powermaxx · Mar 20, 2006

will the trickflow heads come milled to 58cc?
or do i have to do that on my own?

if i have to get them milled i should just buy the afr heads with 58cc chambers so i can put them on out of the box and be done with it.

Not to hijack the thread, but I'm also interested in the twisted wedge possibilities. This summer I'm going to be doing a head and cam. Was thinking about afr 165s or the tw. Also what kind of cam would anyone recommend. I was thinking of the e303 or the trick flow stage 1 but I don't know about compatibility or what would work best.

i made 295rwhp/320rwtq on the combo listed below runnin a 14.0:1 a/f ratio.

that was also before my lightweight flywheel

TFS Twisted Wedge....

vikingpower is right,also the TFS intake valve angle will let you run more lift with the larger vavle than the other heads,and it also helps is flow more.Plus the exhaust port on the TFS seem to be excellant in desing.

i need to have the 58cc chambers though do the twisted wedge offer the 58cc option?

The TW is a 61cc head,to mill it down to 58cc would only be about .0020 off the head.A mahcine shop should do it in a day and not cost more than $150.

But the differnace is about a .3-4 points of compression so I really wouldnt worry,get what head you like.

Now I wouldnt do a 64cc chamber,thats would be a big differance.

powermaxx · Mar 21, 2006

well i rilly want to mill it to like 57 or 56cc chambers but if i got a head with 58 id just leave them.

if i get them milled will the valves hit the pistons?

it would be nice to have 9:5:1 compression on the stock shortblock.

Nope, I had my AFRs milled .024" and it was originally a 60cc head (pedestal mount) on a big cam without any clearance issues. That should've taken my combustion chambers to about 56cc.

o rilly?

so i should just buy the topend kit then i supose.

FastDriver · Mar 21, 2006

I have no idea what a topend kit is.

powermaxx · Mar 21, 2006

go to the trick flow website and look for a topend kit there.

bluevenom867 · Mar 21, 2006

Actualy you can "angle" mill the heads and get even more pvc (piston to valve clearance),it also helps just slighty with flow.

powermaxx · Mar 22, 2006

i think i might just go with an afr 165 58cc chambers, edelbrock intake, and an E-cam.

too much modifying to be done with the trick flow heads.

1badsuv · Mar 22, 2006

edelbrock heads, professional products typhoon and an x-cam, with a 75 mm intake is torquey

FastDriver · Mar 22, 2006

atta boy!

You won't be sorry if you go with the AFRs.

i just found this sweet chart

Too many colors....ugh...

your supposed to pick two heads and compare them.
