Porting the SB head

[lenweiler]

Does anyone know the name of the tool, and who makes it, for measuring wall thickness at the pushrod hole/intake runner wall. Yes, I know one can be made up, but I'd like to save a 'little' time. These things take 40 plus hours as it is.............. Swore I'd never port another set, but, well you know.

I know it cant think of it. Maybe powerhouseproducts.com ?

Helgesen make the E-tool, but I couldn't find any suppliers when I ran an internet search. Hope this helps.

I seen this used in mopar muscle mag. Search there site for a address.

Thanks. But I drew a blank on all accounts. Looks like I'll make one.

Most likely not, the tool on that site has not much use in porting heads.

Not sure if you want to know this, but I use 2 carbide cutters with 6 inch shaft, slide one down the pushrod hole flush against the pushrod wall & line the other one up on the outside against the intake face so they are both parallel to each other & judge the thickness by eye sight, works for me anyways

Along the same idea, but this tool allows accurate measurements at an exact area in the port. Also can be used on the head bolt boss that's upstream, and devides the intake runners. Cheeper than a sonic tester.

To be honest, I've always done the eyeball thing too, using a couple of pushrods. I know it's not as accurate as a tool made for the job, but for a street head where you don't need to go too crazy it seems to work - no breakthroughs or cracking on the last few sets of heads. From what I've read (on iron heads anyway - no experience with anything more exotic on mopars yet) cleaning up the the bowl area gives you more flow improvement than carving a ton of material out of the pushrod pinch anyway, so I stay a little conservative there. Still haven't come up with anything through internet searches for the E-tool though - God knows where you're supposed to buy these things...
