Okay, so with the horror stories I've read about people dropping valves and what not with 2step launch control I now want to upgrade my valvetrain as a reliability piece of mind.

Okay, so far I've narrowed it down to a couple of choices for me to chose from:
InlinePro
ScienceOfSpeed
Supertech
Brian Crower

Which one do you suggest?
Personally I'm biased towards Supertech simply because I've had nothing but good experience with them on past motors. Also well priced

SoS I've never heard anything bad about them in general, but I cant seem to find any info on peoples experience with their valvetrain. Cheaper then the rest so far from what I've found.

IP is simply more pricey then the rest. I'm sure they make good shit, but its a bit pricey.

Brian Crower, well priced, good reputation. What more to say?

I've looked at the prices for Dual Valve springs, retainers, and spring seats.

Out of those which ones have you had best experiences with?

Thanks ahead of time!

Also looking for a ported head possibly if anybody has one for sell.

 

The IP stuff is supposedly Supertech but is over priced. I went with Mike Laskey and got all Supertech stuff; inconel ex valves, nitrite coated ss in valves, dual valve springs with spring locators and ti retainers for $675 shipped. I took the head to a good local head shop for the build and machining and that only cost me $175. There I got a hot tank, bead blast, 3 angle valve job, valves lapped, head checked for cracks, new valve seals, new ex valve guides, decked for straightness and everything put together and ready to go. All in all, the whole build cost me about $850 and about $300 or so cheaper than going with IP.

 

Mike is great, super nice guy to deal with that is where I bought my supertech stuff too.

 

Pretty sure Laskey is using portflow which is the head I got . I cant say anything bad about it for sure. Price was pretty damn good . The owner of portflow called me and talked to me for awhile answering all my questions as well and I didnt even ask him to do so. So +1 to them

 

I was going to say Supertech as well. Thats what Im building my head with

 

I used supertech as well.

 

^ When are you going to be done with the new project?

 

dsddcd and trbokev i believe both used supertech.

supertech is what i am planning on using when i get my extra head to build.

 

never
