Trick Flow PowerPort 290 Cylinder Head question
« on: January 05, 2011, 09:35:17 PM »
These heads require CJ headers per their spec sheet.   Oh by the way chebby boys we are talking Big Block Ford here...

Does anyone know for SURE,  will the long bolt logs cover the exhaust ports?   I'm hoping someone is using this combination so I don't have to pull a log and compare it to a gasket port.

It's cold outside, thank you in advance!

It will be necessary to gasket match the exhaust of the thru-transom logs so as to not obstruct the cylinder head's exhaust port exit.  The port roof heights are different between the two components in question and as I recall the exhaust header mounting holes in the TFS Street/Strip head are relocated on those heads.

Will the long-bolt thru-transom exhaust's mounting flanges cover the roof of the exhaust ports on those heads? I can't recall with 100% certainty that they will, but some simple measuring can easily answer that question...just compare the exhaust bolt hole-to-roof dimensions between the two parts. As I recall, no problem sealing there, it's only the port alignment. Place the gasket against the cylinder head's exhaust flange, align the mounting holes and mark the roof of the port on the gasket, then transfer that gasket to the thru-transom flange and mark the height to which the log's roof will need to be raised relative to the mounting bolt holes between the two parts.

Perhaps someone here can provide you with cylinder head dimensions (bolt center to roof height) for you to compare to your exhaust dims before you purchase the heads, but as I recall it's not major issue, just another mod

Here inlies the problem... both boats are under 3 covers, two inches of snow and it's 17 degrees outside.

That's why I was hoping someone knew if this would work from first hand experiance.   Other wise,  it's going to be a while till we can pull a log and do the gasket match check.

It really sucks in the winter  :banghead:

Are any of you guys running these heads?   Just wondering what your opinion is of them.

I wonder what the dyno would see between the trick flows and the edelbrocks at 5500 rpms.
We'll probably never know...
