Trickflow 170's overkill on close to stock 302?

My original engine build up plans, of which I have all the parts for, is GT40P heads, Explorer intake and injectors, stock cam, 65mm TB, and shorty headers. Car is an 86 GT with 3.55 gears, modified exhaust.
I am considereing the Trickflow twisted wedge 170 heads in large part because of the ease, bolt on and go, versus checking PTV and possibly having to get the valve reliefs done by someone. And I still have to get the GT40P's checked and could be looking at some machining work costs. I really the idea of taking off weight from up higher on the front end of the car. I was going to stay with the stock GT cam, so no plans to switch from speed density. Would I loose power in the lower rpm's versus the smaller valves and ports on the GT40P heads? Would I really gain much considering the mildness of the rest of the engine? Thanks greatly for any feedback.

Definitely not overkill. I have those heads and a can from ed on a stock bottom end and I've run in the 11s at 116+. I'll have dyno numbers this weekend. I know there's some others here that will chime in and agree

Go with the trickflow you can sell the gt40 to help offset some of the cost.

As you can see in the thread listed above the 170cc heads are not overkill. That head will work great on your combination and still give you room to grow in the future. If you have any questions feel free to call me at 330-630-1555.


Thanks, Gregg

Not at all, I run a set of ported 170's on a mostly stock shortblock, in a 4 door sedan with no issues. Don't believe the internet myths.

1985 LTD LX, various mustang stuff on it.

Those heads are great and leave lots of room for growth. Last year I pulled 637/573 with those heads untouched. Lots of bang for the buck.

Thanks for all the replys and info. I believe I'll be fine with the 170's. And should be a no hassle install on the '86. There is a guy at work who will buy my GT40P's for $250 and I ended up NOT buying a set of NOS back window louvers for $500, so I'm already close!
