Hello, I'm another new guy to the forum, haven't posted my pics yet but I will. I want to start my engine build for my 1950 1/2 ton. I'm using a 54 235 out of a "big bolt" my brother had. I already found a T5 from an S10 for a transmission.

I'm building a rat rod and want to hop up the 235 a little bit. Planning on getting a dual 1 barrel intake and fenton headers. I havent found any answers by searching or in the tech tips so if these questions have already been answered I apologize.

Does anyone make domed 9, 9.5 to one pistons? Or do I have to go custom? I know that I can mill the head down but from what I read it doesn't bring it up to 9.

And what sizes valves should I look for? I read an artical from another post were they ported the intake side of the head to 1.625 on the bowl, and 1.5 on the runner. I was planning on goin that route.

I'm sure I'll have more questions later but this is were I'm at know. If anyone has any experiance or sources for parts I would apriciate it. thanks
