Nice #'s. The price is kinda misleading though because most guys would definitely upgrade springs.

Any chance on getting a dyno of these heads with a smaller (224ish) cam?

Actually we've sold as many with the standard spring as heads with double springs. Some guys already have spring kits

Send me the cam and I'll test it in my car.






I currently don't know anyone local with a 224ish cam that is planning on heads though.

I'll post another graph if I swap cams to the MS3 and when (if ever) I install an underdrive pulley.

Do you lose any P2V clearance with these heads? Just a tad from the slight mill?

I lost a very slight amount although not enough to worry about. I would have had to flycut the pistons on the intake side if I had 2.04" valves, as the 235/240 camshaft gets close on the intake. 2.02" should be fine if I go under the knife again for an "update".

Since there is only 30 of my cam in existance, its probably not a issue unless its bigger than a MS3.

Joseph, any speculation how my car would dyno NA with those TSP/PRC heads and my mods in sig? I'm basically running a full bolton 233/239 @ 113 car. M6.

By the way, my cam scares people. I know I made the right choice going with TSP.

Yeah, any testing done with smaller cams. Not everyone has a big cam.
