Another head gasket thread

[Scoobum]

PM is working...as far as I know...and...y ou've got issues.

[Just a Six?]

Try the RJC. I have used a few sets of Victors & they are good gaskets but the RJC will take a bit more punishment & with all the goop on them they seal up pretty good. Get 2 heat guns & while on the stand you can heat cycle the heads one at a time for the retorque per instal instructions.

How do you heat cycle the heads with a heat gun? Unless it has a BTU rating on par with Godzilla

Our plan is to finish the season with the new gaskets and retorque them over the winter. I think the Canadian heat lights are more powerful than U.S., that' how he gets it done.

Zackly, that's what I mean. Dave, yours needs plugged in.

I think Ed's runs on beans and burritos.

Ed - I remember reading that one uses 2 heat guns, one per coolant passage in the front of the block. How many hours do you have to have them running?

Just got back from machine shop. Was thinking just resurface headers but too many cracks at existing welds, I just as soon replace them. I am totally lost on whose headers to use. I'm thinking stainless steel, but best flow and sealing is my main concern. Steve, we decided to use Cometics. I talked to Cometics Rep at Chryslers at Carlisle and like what he had to say, but I am also worried about your coolant leak concerns. What made up my was the fact that both steel shim and Cometics should have the same surface prep.

No reason to use anything but stock for headers. Some have had good luck with the Chinese eBay headers.

[Steve Wood]

they are great hgs if they work.

Shims, we glue them on...no leaks

Cometics are made to use without glue...but, I see people using copper coat, opening the layers and spraying stuff in between, etc...let us know how they work

[Pyro6]

I'll let you know Steve. It's a tough decision and any of the suggested gaskets could go either way. I'm already missing a race this weekend, I would prefer to keep the wrenching part for the winter.

[/quote] But don't you think I could gain a little more HP with other headers??? (mot Chinese) I was looking at Kirban's and Cotton's.

I am FAR from an expert - but after all these years reading TR threads - I have heard that there's very little gain, if any, by using aftermarket headers. Unless you want to try for 9 second quarter miles.

I seem to remember that stockers are good to low 10's?
