New Trick Flow FE cylinder heads & Intake

[andyf]

The FelPro gaskets seem to be a nice fit for the Trick Flow ports. I also checked the Cometic gaskets and they fit, but were oversize. I think the Cometic gasket is designed for a much taller intake port and a bigger exhaust port.

This engine will be nice looking with the factory manifolds, tunnel wedge type intake and tall valve covers. Should drive nice with the dual throttle bodies.....

Andy, be careful of those gaskets, those appear to be the dreaded Fel-Pro "Print-O-Leak" gaskets.  Lots of folks have had problems with those, do a search and you will find pictures of those gaskets blown out on the bottom of the ports, causing vacuum leaks or in some cases water leaks.  I'd stick with the Cometics or the some Mr. Gasket composition gaskets.

Got the heads mocked up on the 482 shortblock. Manifolds bolt on okay, gaskets seem to line up pretty well, intake bolts on, etc. Might need some minor tweaking here or there but shouldn't take a bunch of work.

The valve springs are for a hyd roller even though the heads come with Ti retainers. I don't understand the thinking behind that so we'll need to swap on some solid roller cam springs and then use the hyd roller springs on a different engine. Trick Flow usually puts solid roller springs on the heads that have Ti retainers but guess they didn't think anyone would want to run a solid roller FE??

Light valves and light retainers are a good idea for a hydraulic roller FE that's going to try to get over 6000 rpm.  Plus it's marketing and eye candy for all the guys with lower rpm stuff.

If they intend for guys to use solid roller camshafts, then they need to offer an option for T&D race rocker mounting so that guys won't pull the rocker stand studs out of the heads.  If you're over 600 lbs open pressure, you should be eyeballing this too.  I know you said you're going with the Comp Cams rockers, but none of us use those, so there's not a lot of data on them.  I would at least change the helicoils out to big inserts.  Once you pull a rocker stand stud out of the head, you never wanna do it again.

Yeah, I don't think you want to use those intake gaskets unless you are Canadian and not using antifreeze.

I've seen them deteriorate and "squirm" around on my own 428.  I'm using Mr. Gasket 202A's now.  Much better.

The Mr.Gasket 202A's are easy to trim to the port size, too.   Though they are limited in how far you can trim them, if your ports are very big.

Anyone else using the new one piece rear main seal from Roush? Seems like a nice part but a little hard to find.

Thanks Barry, I'll take a look at that. I have the Cometic gaskets on hand but they have really big ports in them. Might work okay, just looks weird.

Same item Kaase uses on 460s.  Formed in a circle - slice it and glue the pieces together around the crank before setting it in the block

I used one on a Pontiac once.  It leaked.

How do you get it over the flywheelflange is it split somewhere?

[blykins]

You split it. 

You cut it with a razor blade and then stretch it over the crankshaft.  Split goes towards the top of the block.

OK then you must be able to glue it together with locktite i think.
Locktite have a kit for making O-rings from a roll of rubber strip
that you cut to length and glue together so...If its needed i don't
know but i don't think it would hurt either

Hate to drag the thread OT, but I have a set of the standard 1247's that I was planning on installing in the next few days. Dang cork at the front and rear of the intake have been leeching oil and making a mess since I put the motor together, finally mad enough to replace them. So does the S3 variant fare better or should I just avoid the "Print-O-Leak" all together and get the Cometic/ Mr gasket?
